Executive Summary
Polymeric Materials (688503.SH) has released its interim financial results for the first half of 2025 (1H25), revealing a period of strategic transition amidst industry-wide margin compression. While the company reported a year-on-year decline in net profit attributable to shareholders of -39.58% to CNY 181 million, its core operational metrics demonstrate resilience. Specifically, the volume of photovoltaic (PV) conductive paste shipments remained robust, exceeding 930 tons in 1H25, with a notable sequential growth in 2Q25 driven by improved downstream battery utilization rates and market share gains.
The primary investment thesis for Polymeric Materials is shifting from pure volume expansion in traditional silver pastes to a dual-engine growth model: (1) The industrialization of copper paste technology, a critical cost-reduction pathway for the PV industry, and (2) Diversification into non-PV electronic functional materials, establishing a second growth curve. The company is scheduled to launch its second-generation copper paste product in 3Q25, leveraging its accumulated know-how in material formulation, equipment matching, and process parameters for technologies such as full-open mesh screens and 0BB (Zero Busbar).
Despite the near-term earnings headwinds reflected in the compressed gross margins (down 4.01 percentage points to 6.89% in 1H25), we maintain our OUTPERFORM rating. We have adjusted our earnings forecasts for 2025-2027 to reflect the current competitive landscape and slower-than-expected margin recovery. However, we believe the market has not fully priced in the long-term value accretion from the successful commercialization of copper pastes and the diversification into high-value electronic materials (RF devices, LTCC, PDLC, etc.). At current valuation levels (2025E P/E of ~32.7x), the stock offers an attractive entry point for institutional investors seeking exposure to next-generation PV metallization technologies and advanced electronic materials, provided they can tolerate short-term volatility associated with technology iteration risks.
Key Takeaways
1. Financial Performance Analysis: Revenue Resilience vs. Profit Compression
The 1H25 financial results highlight a divergence between top-line stability and bottom-line pressure, a trend characteristic of the current maturation phase in the PV supply chain.
- Revenue Stability: The company generated total operating revenue of CNY 6.435 billion in 1H25, representing a modest year-on-year decline of 4.87% compared to CNY 6.765 billion in 1H24. This relative stability in revenue, despite significant price erosion in the PV sector, underscores the company’s ability to maintain shipment volumes and defend its market position.
- Profitability Decline: Net profit attributable to the parent company fell by 39.58% to CNY 181 million. More critically,扣非归母净利润 (Net profit deducting non-recurring items) dropped by 52.66% to CNY 156 million. This sharper decline in core earnings indicates that the pressure on operating margins is structural rather than transient, driven by intense competition in the silver paste market and the high R&D costs associated with new product development.
- Quarterly Trend: In 2Q25 alone, the company recorded a net profit of CNY 91 million, a significant 59.22% year-on-year decrease. However, on a sequential basis, this represents a slight improvement of 1.51% over 1Q25, suggesting that the rate of profit deterioration may be stabilizing as the company optimizes its cost structure and product mix.

Analysis of Margin Compression:
The gross margin contracted by 4.01 percentage points to 6.89%. This compression is primarily attributed to:
1. Price Wars in Silver Paste: The PV industry’s drive for cost reduction has intensified competition among paste suppliers, forcing price concessions.
2. Product Mix Transition: As the company ramps up production of new products like copper paste, initial yields and scale efficiencies are lower than mature silver paste lines, temporarily dragging down overall margins.
3. Raw Material Volatility: While silver prices have been relatively stable, the cost pass-through mechanism in the highly competitive downstream market is imperfect, squeezing converter margins.
Despite the margin pressure, the company demonstrated effective expense management. Selling expenses decreased by 20.77% to CNY 19.96 million, and administrative expenses fell by 7.69% to CNY 55.22 million. Financial expenses also saw a significant reduction of 41.62% to CNY 27.11 million, likely due to optimized debt structures or lower interest rates. These operational efficiencies partially offset the gross margin decline, preventing an even steeper drop in operating profit.
2. Core Business Dynamics: PV Conductive Paste Market Leadership
Polymeric Materials continues to solidify its position as a leading supplier of PV conductive pastes. The fundamental demand driver remains the global expansion of solar capacity, particularly the shift towards high-efficiency cell technologies such as TOPCon and HJT, which require higher quality and specialized pastes.
- Shipment Volume Resilience: In 1H25, the company’s sales volume of PV conductive paste exceeded 930 tons. This volume level is indicative of strong demand retention. Notably, in 2Q25, shipments reached nearly 490 tons, marking a sequential increase from 1Q25. This uptick correlates with higher operating rates at downstream battery manufacturers, suggesting that the destocking phase in the supply chain may be concluding, and production activity is normalizing.
- Market Share Stability: Amidst a fragmented and competitive landscape, Polymeric Materials has maintained a stable market share. This stability is crucial as it provides the cash flow base necessary to fund R&D for next-generation technologies. The company’s ability to hold share despite margin pressures suggests strong customer stickiness, likely driven by technical service capabilities and consistent product quality.
- Technology Alignment: The company’s product portfolio is well-aligned with the industry’s transition to N-type cells. As PERC capacity is phased out, the demand for TOPCon and HJT pastes—which command higher technical barriers and potentially better long-term margins—is rising. Polymeric Materials’ focus on these advanced nodes positions it to benefit from the structural upgrade in the PV cell market.
3. Strategic Catalyst: Copper Paste Industrialization
The most significant potential value driver for Polymeric Materials is its aggressive pursuit of copper paste technology. Copper paste is widely regarded as the "holy grail" for cost reduction in PV metallization, given that copper is significantly cheaper than silver. However, technical challenges related to oxidation, adhesion, and conductivity have historically hindered its mass adoption.
- Progress and Know-How Accumulation: The company has made substantial progress in overcoming these technical hurdles. It has developed comprehensive "Know-how" covering:
- Material Formulation: Developing proprietary alloys and additives to prevent copper oxidation and ensure reliable electrical contact.
- Equipment Matching: Collaborating with screen printing equipment manufacturers to optimize the printing process for copper paste’s different rheological properties.
- Process Parameters: Fine-tuning sintering temperatures and atmospheres to maximize conductivity without damaging the silicon wafer.
- Product Iteration: The company is customizing copper paste products for different technical routes and specific customer requirements. It is actively optimizing its formulations for emerging technologies such as Full-Open Mesh Screens and 0BB (Zero Busbar). These technologies are critical for reducing silver consumption further and improving cell efficiency.
- Timeline for Commercialization: A key milestone is the planned launch of the second-generation copper paste product in 3Q25. This timeline suggests that the company is moving from the pilot/R&D phase to early commercial validation. Successful deployment of this product could significantly enhance the company’s competitive moat and open up a new, high-margin revenue stream as the industry seeks alternatives to silver.
- Strategic Implication: If Polymeric Materials can achieve stable mass production and yield rates with its copper paste, it will not only reduce its own raw material costs but also offer a compelling value proposition to downstream cell makers facing margin pressures. This could lead to a re-rating of the stock as a technology leader rather than just a commodity supplier.
4. Second Growth Curve: Diversification into Non-PV Electronic Materials
Recognizing the cyclical nature of the PV industry, Polymeric Materials is strategically diversifying into the broader electronic functional materials sector. This move aims to create a "second growth curve" that is less correlated with solar cycles and offers higher value-added opportunities.
- Platform-Based Expansion: Leveraging its core competency in paste technology (particle dispersion, binder systems, rheology control), the company is expanding into adjacent markets. This platform approach allows for efficient R&D resource allocation and faster time-to-market for new products.
- Product Matrix: The company has formed a multi-dimensional product matrix covering:
- RF Devices: Pastes for radio frequency components, critical for 5G and future communication infrastructure.
- Chip Components: Materials for passive components like capacitors and inductors.
- PDLC (Polymer Dispersed Liquid Crystal): Conductive materials for smart glass applications, a growing market in automotive and architectural sectors.
- EC (Electrochromic) Conductive Adhesives: For smart windows and displays.
- LTCC (Low-Temperature Co-fired Ceramic): Essential for high-frequency, high-density electronic packaging.
- High-Performance Thermal Materials: Addressing the increasing thermal management needs in high-power electronics and EVs.
- Market Potential: These segments are characterized by higher technical barriers, longer customer qualification cycles, but also higher margins and greater stability compared to the commoditized PV paste market. Success in these areas will diversify the company’s revenue base and improve its overall profitability profile over the medium to long term.
- Current Status: While the report does not provide specific revenue breakdowns for these non-PV segments, the emphasis on "active layout" and "precise entry" suggests that these businesses are in the early stages of scaling. Investors should monitor future quarterly reports for signs of revenue contribution from these segments as a key indicator of successful diversification.
5. Valuation and Earnings Forecast Adjustments
In light of the 1H25 results and the evolving competitive landscape, we have revised our earnings forecasts for Polymeric Materials.

Risks / Headwinds
Investors should carefully consider the following risks, which could materially impact the company’s financial performance and stock price:
1. New Product R&D and Commercialization Risk
- Technical Failure: The development of copper paste and other advanced electronic materials involves complex chemical and physical processes. There is a risk that the second-generation copper paste launched in 3Q25 may not meet performance benchmarks (conductivity, adhesion, reliability) required by major cell manufacturers.
- Yield Issues: Even if the product meets technical specs, achieving high manufacturing yields at scale is challenging. Low yields would erode margins and delay profitability.
- Customer Qualification Delay: The PV industry is conservative regarding material changes due to the high cost of failure. Qualification cycles for new pastes can be lengthy (6-12 months). Delays in customer adoption would push back revenue recognition.
2. Photovoltaic Policy and Macro Economic Risk
- Policy Shifts: The PV industry is heavily influenced by government subsidies, trade policies (e.g., tariffs in the US, EU, India), and carbon neutrality targets. Any adverse policy change in key markets could dampen global demand for solar installations, directly impacting paste volumes.
- Interest Rates: High interest rates can increase the cost of capital for solar project developers, potentially slowing down installation rates and affecting the entire supply chain.
3. Downstream Expansion and Demand Risk
- Overcapacity in PV Cells: The PV cell manufacturing sector is currently experiencing significant overcapacity. This leads to intense price competition among cell makers, who then pass this pressure upstream to material suppliers like Polymeric Materials. If downstream profits remain depressed, their ability to pay premium prices for advanced pastes will be limited.
- Slower-than-Expected Demand: If global solar installation growth slows due to economic recession or grid integration issues, the demand for conductive pastes will grow slower than forecasted.
4. Competitive Landscape and Price War
- Intensified Competition: The conductive paste market has seen new entrants and aggressive expansion by existing players. This could lead to prolonged price wars, further compressing gross margins beyond current levels.
- Substitute Technologies: While copper paste is a cost-reduction strategy, other metallization technologies (e.g., plating, hybrid approaches) are also being developed. If a competing technology proves superior or cheaper, Polymeric Materials’ investment in copper paste could become stranded.
5. Technology Route Substitution Risk
- Cell Technology Shifts: The PV industry is dynamic. A sudden shift in dominant cell technology (e.g., from TOPCon to HJT or Perovskite tandem cells) could require different paste formulations. If Polymeric Materials fails to adapt quickly to the new dominant technology, it could lose market share.
- Silver Thrifting: Continuous efforts to reduce silver loadings per cell (thrifting) mean that even if solar installations grow, the total volume of paste required might grow at a slower rate, or the value per watt might decline.

Deep Dive: The Copper Paste Opportunity
To fully appreciate the investment case for Polymeric Materials, it is essential to understand the strategic importance of copper paste in the PV industry.
The Silver Cost Problem
Silver has traditionally been the primary conductor in PV cell metallization due to its excellent conductivity and stability. However, silver accounts for a significant portion of the non-silicon cost of a solar cell. As the industry scales to terawatt levels, the demand for silver threatens to outstrip supply, driving up prices and constraining industry growth. Reducing silver consumption is therefore not just a cost-saving measure but a strategic imperative for the sustainability of the solar industry.
Why Copper?
Copper is approximately 1/100th the price of silver and has comparable electrical conductivity. Replacing silver with copper in the metallization process could reduce the cost of the paste by over 50%, significantly lowering the overall cost of solar modules. This would make solar energy even more competitive against fossil fuels and enable further global adoption.
Technical Challenges and Polymeric Materials’ Solution
The main challenge with copper is its tendency to oxidize, which increases resistance and degrades cell performance. Additionally, copper atoms can diffuse into the silicon wafer, creating defects that reduce efficiency.
Polymeric Materials’ approach involves:
1. Advanced Encapsulation: Developing specialized organic binders and coatings that protect copper particles from oxidation during storage, printing, and sintering.
2. Barrier Layers: Integrating barrier layers in the cell structure or the paste itself to prevent copper diffusion into the silicon.
3. Low-Temperature Sintering: Optimizing the sintering process to minimize thermal stress and oxidation.
The company’s "Know-how" in these areas, accumulated through years of R&D, is a significant competitive advantage. The launch of the 2nd Generation product in 3Q25 suggests that these technical hurdles are being overcome.
Market Size and Potential
If copper paste achieves even a 10-20% penetration rate in the TOPCon and HJT markets by 2027-2028, the addressable market for copper paste suppliers will be substantial. Given Polymeric Materials’ early mover advantage and strong customer relationships, it is well-positioned to capture a significant share of this emerging market. This potential revenue stream is currently not fully reflected in the consensus estimates, representing a hidden value option for investors.
Deep Dive: Non-PV Electronic Materials Diversification
The diversification into electronic materials is a strategic move to de-risk the business and tap into higher-growth, higher-margin sectors.
Target Markets
- 5G and Communications (RF Pastes): The rollout of 5G and the future development of 6G require high-frequency, low-loss electronic components. RF pastes are critical for these components. This market is growing steadily and is less cyclical than PV.
- Automotive Electronics (EC/PDLC): The trend towards smart cockpits and electric vehicles is driving demand for smart glass (PDLC/EC) and high-reliability electronic components. Polymeric Materials’ conductive adhesives and pastes are suitable for these applications.
- Advanced Packaging (LTCC): As semiconductor packaging becomes more complex (SiP, Fan-Out), LTCC substrates are gaining importance. Providing materials for LTCC manufacturing places Polymeric Materials in the high-value semiconductor supply chain.
Synergies
The core technology underlying all these products is functional paste formulation. This includes expertise in:
* Particle size distribution and surface treatment.
* Rheology control for precise printing.
* Binder and solvent systems for optimal curing.
By leveraging this common technology platform, Polymeric Materials can spread its R&D costs across multiple product lines and accelerate time-to-market for new applications. This platform strategy is more efficient than developing each product line from scratch.
Long-Term Impact
Over the next 3-5 years, we expect the non-PV segment to contribute an increasing percentage of total revenue and profit. This will:
* Smooth Earnings Volatility: Reduce the impact of PV cycle downturns.
* Improve Margins: Electronic materials generally command higher gross margins than commodity PV pastes.
* Enhance Valuation: Diversified tech-materials companies often trade at higher multiples than pure-play PV suppliers.
Final Remarks
Polymeric Materials stands at a pivotal juncture. The short-term financial results reflect the harsh realities of the current PV market, but the strategic initiatives undertaken by the management—specifically in copper paste and electronic materials—position the company for sustainable long-term growth.
For institutional investors, the key is to look beyond the 1H25 earnings miss and focus on the execution of the strategic roadmap. The successful launch of copper paste and the scaling of the electronic materials business are the true drivers of future value. We believe the market is currently underestimating these potentials, making Polymeric Materials an attractive OUTPERFORM candidate for portfolios with a medium-to-long-term investment horizon.
