Introduction
Shandong Longhua Polymer Material Co., Ltd. (山东隆华高分子材料有限公司) is a wholly owned subsidiary of Shandong Longhua New Material Co., Ltd. (stock code 301149), based in Gaoqing County, Zibo, Shandong Province, China. The company operates in the engineering plastics and polymer materials segment of the plastics industry, with a focus on PA66 resin and specialty nylon materials for fiber-grade and engineering-plastic applications.
Longhua Polymer Material is positioned within a broader Longhua New Material group that also develops and produces polyether polyols, polymer polyols, and polyether amines, giving the enterprise a wider materials platform across polyurethane intermediates and polyamide products. Its industrial base in Gaoqing has been described as a major new-materials site, and the company has been associated with a large PA66 expansion program intended to deepen its role in China’s nylon value chain.
History and Development
Longhua New Material was founded in 2011, and the group’s later expansion into polyamide materials created the corporate background for Longhua Polymer Material. Longhua Polymer Material itself was established on 22 March 2022 as a wholly owned subsidiary of the listed parent company.
A major development milestone came with the launch of the 108万吨/年 PA66 project, announced by the parent company and implemented through Longhua Polymer Material as the project entity. Public filings show that the project was designed in phases at the Gaoqing chemical industry park, with an initial 4万吨/年 PA66 unit completed and entering commissioning and trial production in early 2025.
A further milestone was the company’s product-structure adjustment in 2025, when the planned output mix for the PA66 platform was broadened from a single-resin focus to a nylon product portfolio including PA66, long-chain nylon, transparent nylon, and high-temperature nylon.
Business Operations and Segments
Longhua Polymer Material is organized around the production of nylon 66 and specialty nylon resins, supported by technical services and new-materials development activities.
Its operating scope includes:
- Fiber-grade PA66 resin
- Engineering-plastic PA66 resin
- Specialty nylon resins
- Chemical product sales and production
- New-materials technology research and development
The company’s business model is tied to downstream industrial customers that require consistent polymer performance, processability, and application-specific formulation support.
Products and Technologies
The core product line is PA66 resin, supplied in both fiber-grade and engineering-plastic grades. These grades are used differently: fiber-grade material is typically intended for textile and reinforcement applications, while engineering grades are formulated for molded parts that require strength, heat resistance, and durability.
The company has also linked its platform to specialty nylon development, which, according to company materials, includes products such as:
The parent group’s technical platform also covers polyether polyols, polymer polyols, and polyether amines, indicating experience in polymer synthesis, formulation, and customer-specific customization across adjacent materials markets. Company descriptions emphasize the ability to develop products according to different customer demands, which suggests an emphasis on tailored resin properties rather than commodity-only output.
Applications and End Markets
Longhua Polymer Material’s nylon products are described as serving a range of industrial applications, including:
- High-end electrical and electronic components
- High-speed rail
- Automobiles
- Aviation
- 3D printing engine parts
- Airbags
- Tire cord fabrics
For the broader group, polyether and polymer polyol products are used in flexible foam, car seats, coatings, adhesives, sealants, and elastomers, linking the enterprise to both polyurethane and engineering-plastics supply chains.
Global Presence and Market Position
The company is headquartered at No. 289, Zhimaihe Road / Weigao Road area, Gaoqing County, Zibo City, Shandong Province and operates from a site described as covering more than 800 acres with more than 500 employees.
In the market, Longhua Polymer Material is best understood as a specialized upstream-to-midstream materials producer rather than a broad diversified plastics conglomerate. Its significance lies in the scale of its parent group’s polymer platform and the strategic build-out of the PA66 chain, which connects it to major domestic downstream sectors that require high-performance nylon materials.
Research and Development
The company and its parent emphasize new-materials R&D, process development, and customer-specific product design. Public corporate descriptions refer to a qualified R&D team and “leading” production and R&D bases in polyether polyols, polyether amines, PA66 resins, and specialty nylon resins.
The 2025 product adjustment toward a broader nylon portfolio indicates a development strategy centered on product differentiation and application-specific resin grades, rather than a single standard commodity resin line.
Sustainability and Environmental Initiatives
Corporate descriptions present the business as focused on safe and environmentally oriented new-material solutions. The group’s broader portfolio includes materials marketed for performance and environmental characteristics, particularly in relation to polyether and polyurethane intermediate products.
The 108万吨/年 PA66 project was subject to formal environmental review and public participation procedures, reflecting the regulatory framework governing large chemical and plastics installations in China. The project structure and permitting process indicate that environmental compliance is an integral part of the company’s industrial expansion.
Financial Performance and Economic Impact
As part of a listed group, Longhua Polymer Material contributes to the parent company’s industrial footprint and capital deployment in high-performance materials. The PA66 project has been described in industry reporting as a major investment, with an estimated total of 73 billion yuan for the full 108万吨/年 program.
The project has also been framed as an extension of Shandong’s nylon supply chain, particularly through the downstream conversion of upstream diamine feedstocks into PA66 and specialty nylon materials. This places the company within a broader regional industrial strategy focused on chemical materials integration and value-chain expansion.
Quality Management and Certifications
Longhua New Material has been described in industry materials as a high-tech enterprise and a Shandong Province manufacturing single-champion enterprise, and the subsidiary benefits from that broader corporate positioning. These designations are commonly associated with sustained technical capability, process discipline, and industrial specialization in China’s materials sector.
Innovations and Future Outlook
The company’s future trajectory is closely linked to the development of its PA66 and specialty nylon platform. The phased expansion from an initial 4万吨/年 unit to a larger multi-product nylon base suggests a strategy built around scale, product diversification, and downstream application reach.
If the broader project is completed as planned, Longhua Polymer Material would reinforce its role as a significant participant in China’s engineering-plastics and nylon materials ecosystem, especially in sectors demanding lightweight, heat-resistant, and mechanically robust polymers.
