China's "14th Five-Year Plan for Plastic Pollution Control" proposes that by 2025, the amount of plastic waste landfilling will be significantly reduced, and the recycling rate of plastic waste will reach 60%. This plan encourages the research, development, and application of biodegradable materials, providing clear policy direction and financial support for the green transformation of the compatibilizer industry, strongly driving technological innovation and market expansion in the sector.

These policies not only provide direction for the compatibilizer industry but also accelerate companies' green transformation through specific incentives such as tax benefits, green certifications, and R&D subsidies.

2. Technological Breakthroughs: Intelligence and Multi-Functional Integration Lead Innovation

At the technological level, compatibilizers are evolving from single-function to intelligent and multi-functional integrated solutions.

Temperature-sensitive compatibilizers are on the verge of commercialization in 4D printing materials, dynamically adjusting material properties through temperature changes, offering new possibilities for aerospace, flexible electronics, and other fields. For example, a well-known aerospace manufacturer has successfully applied temperature-sensitive compatibilizers in the development of new materials, significantly enhancing the materials' adaptive capabilities. Companies like Ningbo Nengzhiguang have developed flame-retardant/compatibilizer composite compatibilizers, successfully entering the supply chain for new energy vehicle battery encapsulation materials and addressing dual challenges of material compatibility and safety.

Furthermore, low-molecular-weight reactive compatibilizers have achieved a penetration rate of over 12% in the field of recycled plastic modification, enabling efficient regeneration of waste plastics through chemical bonding and supporting the implementation of the "circular economy." According to data from CMPE Aibang, the penetration rate of intelligent responsive compatibilizers in the electronic and electrical appliances sector has reached 20%, with the market scale expected to exceed ¥1 billion by 2025.

3. Application Expansion: New Energy and Electronic Information Drive Demand Surge

On the application end, the lightweighting of new energy vehicles and the upgrading of the electronic information industry have become core engines driving the demand for compatibilizers. According to statistics, the scale of China's compatibilizer market is expected to exceed ¥8 billion in 2025, with the new energy sector accounting for 25%.

In the new energy vehicle field, compatibilizers enhance the interfacial bonding strength between plastic alloys and carbon fibers, helping to reduce battery pack weight by 20% and costs by 30%, enabling automakers to balance range and cost. For example, Tesla has used compatibilizer technology in its latest models, significantly improving overall vehicle performance.

In 5G communication equipment, higher requirements for heat dissipation materials have led to the application of polyurethane compatibilizers developed through collaboration between DuPont and Wanhua Chemical in heat dissipation modules, significantly improving the thermal conductivity and stability of the materials.

Additionally, the application potential of compatibilizers in emerging fields such as medical devices and photovoltaic encapsulation continues to expand. For instance, in the medical device field, biocompatible compatibilizers are used to manufacture advanced drug carriers and artificial organs, not only improving the reliability of medical equipment but also providing better treatment outcomes for patients.

Global demand for compatibilizers in the plastics industry is expected to grow from 2.5 million tons in 2023 to over 3 million tons in 2025, with an average annual growth rate of 6%.

4. Industrial Restructuring: Leading Companies Secure High-End Positions, Domestic Substitution Accelerates

In terms of competitive landscape, industry concentration is further increasing, with the CR5 reaching 31.7%. CR5 refers to the combined market share of the top five companies in the industry, a metric commonly used to measure market competition and concentration.

Leading companies are enhancing their market competitiveness through technological positioning and industrial chain integration. International giants like Arkema have invested $230 million to establish an Asia-Pacific R&D center in Zhangjiagang, focusing on bio-based technologies. Domestic companies, leveraging rapid response capabilities and localization advantages, are breaking through. Lushan New Materials, for example, has adopted an integrated "resin synthesis-end application" model to reduce supply chain risks.

The increase in CR5 may somewhat limit the survival space for small and medium-sized enterprises but also stimulates technological innovation and diversified development.

Import substitution has been partially achieved in segments such as photovoltaic encapsulation and new energy vehicles, with domestic compatibilizers gradually catching up to international brands in terms of performance and cost. For instance, the localization rate of specialized compatibilizers for lithium battery separators has exceeded 60%, with products from certain companies successfully entering the supply chain of CATL, reducing the end-user verification cycle to six months.

5. Challenges and Outlook: Balancing Innovation and Risks, Embracing High-Quality Development

Despite the broad industry prospects, challenges such as technological iteration risks and raw material cost fluctuations remain. Companies need to increase R&D investment to develop efficient low-temperature, low-usage compatibilizers to address cost pressures. At the same time, they must strengthen supply chain resilience to avoid risks associated with price fluctuations of raw materials like polymers. According to data from Zhongyan Wang, raw material costs account for over 40% of compatibilizer production costs, making supply chain management a core competitiveness for companies.

Looking ahead, policy dividends will continue to be released. The "Polymer Material Industry Development Plan (2025-2030)" explicitly lists compatibilizers as a key development direction. Coupled with the explosive growth of the new energy and new materials industries, the compatibilizer market scale is expected to exceed ¥15 billion by 2030, with an average annual compound growth rate of around 12%. Additionally, it is worth noting that research on the application of nanotechnology and bio-based materials in the compatibilizer field is increasing.
