Huizhou District has positioned specialty new materials as its "primary industry," focusing on three key sectors: specialty resins, specialty engineering plastics, and specialty films. The district has established a closed-loop ecosystem spanning "basic R&D—technological breakthroughs—full industrial chain manufacturing." In 2024, the district's new materials industry output value exceeded 116.23 billion yuan, contributing 69% of the district's above-scale industrial output value and 81% of profits, becoming the core engine for high-quality regional economic development.

Industry Status: Three Sectors Advancing Together with Significant Cluster Advantages

Specialty Resin Materials—Pioneer in Domestic Substitution. Led by companies like Xinyuan Technology and Hengtai New Materials, the sector focuses on developing high-end products such as electronic-grade epoxy resins and polyester resins. Epoxy active diluents hold 60% of the national market share, while solid epoxy resins account for 30%. Products are widely applied in chip packaging and new energy vehicles, ensuring supply chain security.

Specialty Engineering Plastics—Breaking International Monopolies. The complete polyimide (PI) industrial chain: Jinshimu Plastic Technology has successfully developed thermosetting polyimide resins with excellent high-temperature resistance and insulation properties, filling domestic gaps. Its subsidiary Huangshan Juxin New Materials has achieved full-chain production from raw material synthesis to precision components, with products holding 70-80% market share in the mold industry.

Polyphenylene sulfide (PPS) emerging force: The 1.6 billion yuan investment in Dongtai Qixin's annual 80,000-ton PPS project targets high-end demands in 5G communications and humanoid robots. With global market potential exceeding 200,000 tons, this project will significantly enhance regional industrial capabilities.

Specialty Film Materials—Green Packaging Leaders. Yongxin New Materials and Yuandian Technology's BOPE films and high-barrier films, featuring puncture resistance and recyclability, are capturing food and daily chemical packaging markets with technical indicators reaching international standards and annual capacity growth exceeding 20%.

Innovation Achievements: Leading in Both Technological Breakthroughs and Digital Empowerment

Intensive Innovation Platform Layout: Leveraging new materials enterprises, the district has established 4 provincial postdoctoral research stations, 10 provincial engineering technology research centers, and 15 provincial enterprise technology centers. Through industry-academia-research cooperation with institutions like the Chinese Academy of Sciences and Sichuan University, the district has overcome "bottleneck" technologies such as electronic-grade curing agents and PI resins.

Digital Empowerment for Green Production: Accelerating digital-physical integration through the "One District, One Industry, One Model" approach, the district is building an intelligent management platform for Huizhou Chemical Industry Park. It has cultivated 22 digital transformation model enterprises, with 15 companies certified as provincial intelligent factories and digital workshops. The chemical park was selected as one of the seventh batch of "Smart Chemical Parks (Construction Phase)" units nationwide, the only one in the province.

Currently, Huizhou District is driving forward with a dual-engine approach of "innovation-driven + cluster ecosystem" to build a specialty new materials industry hub in the Yangtze River Delta region. Specialized policies precisely cover R&D subsidies, equipment upgrades, talent recruitment, and financial empowerment, providing targeted support for specialty new materials industry cluster expansion. The "District Chief + Chain Chief" mechanism ensures rapid project implementation.
