Five Chinese Companies Leading PA66 GF30 Production

CALIFORNIA, CA, UNITED STATES, September 30, 2026 /CourierPR/ -- China’s engineering plastics industry continues to strengthen its supply of glass-fiber-reinforced polyamide compounds for automotive, electrical, industrial, and other demanding applications. Among these materials, polyamide 66 reinforced with approximately 30% glass fiber, commonly designated PA66 GF30, remains an important material option where stiffness, strength, heat resistance, and dimensional stability are required in injection-molded components.

In September 2026, a PA66 resin price index published by Business Analytiq reported Northeast Asian prices at approximately US$2.95 per kilogram and North American prices at US$3.48 per kilogram. The price difference reflects the role of regional supply conditions in the engineering plastics market, while downstream demand continues to support the use of reinforced nylon compounds.

Against this industry backdrop, five China-based companies active in engineering plastics and modified polymer materials are highlighted: Guangdong Wanhan New Material Technology Co., Ltd., operating under the WanHan Plastic brand; Suzhou Xinyite Plastic Technology Co., Ltd.; Haining Huabang Technology Co., Ltd.; Suzhou Huashda Engineering Plastic Co., Ltd.; and Guangdong Shunde Shunyan New Materials Co., Ltd.

Guangdong Wanhan New Material Technology Co., Ltd., operating under the WanHan Plastic brand, provides a broad portfolio of reinforced and application-oriented polymer compounds from Huizhou, Guangdong. The company traces its business history to 2005 and operates from No. 3 Xingqi East Road, Dongxing District, Dongjiang Science and Technology Park, Zhongkai High-tech Zone, Huizhou City, Guangdong Province. Its facility covers approximately 3,275 square meters and has 56 employees, including 12 engineers in research and development.

Within its engineering plastics portfolio, WanHan Plastic offers PA66-WHG30A, a 30% glass-fiber-reinforced PA66 compound designed for injection molding. The published technical data lists a tensile strength of 175 MPa under ISO 527-2, flexural strength of 255 MPa and flexural modulus of 7,000 MPa under ISO 178, notched impact strength of 18 kJ/m² under ISO 179, heat deflection temperature of 220°C under ISO 75-2/B, melt flow index of 20 g/10 min under ISO 1133, density of 1.38 g/cm³ under ISO 1183, and molding shrinkage of 0.5% under ISO 2577. The company identifies these figures as typical technical data for material evaluation rather than guaranteed specification limits.

WanHan Plastic also offers PA66-WHRG30A, a flame-retardant grade for applications requiring additional fire-performance characteristics. Its technical documentation states a UL 94 V-0 classification, with the applicable specimen thickness to be confirmed against the current grade-specific report. The wider product portfolio includes PA66 GF25 and other glass-fiber-reinforced nylon formulations, as well as PA66 GF33, PA6 GF30, PBT GF30, carbon-fiber-reinforced materials, and other modified engineering plastics.

For automotive applications, the company’s reinforced nylon portfolio is relevant to applications such as PA66 GF30 for Automotive Parts, particularly in structural and under-the-hood components where mechanical strength and heat resistance are required. In electrical and electronic applications, formulations for PA66 GF30 for Electrical Connectors can address requirements related to dimensional stability, flame performance, and mechanical integrity.

WanHan Plastic states that its modified plastic pellet production capacity can reach up to 5,000 metric tons per month for PA66 GF30, subject to production scheduling. It also reports a minimum order quantity of 5 kg and a custom-grade lead time of approximately 7-10 days. The company reports an export ratio of around 70% and customers in more than 30 countries. Its management systems include ISO 9001:2015 quality management, ISO 14001:2015 environmental management, and ISO 45001:2018 occupational health and safety certification, with the stated certification scope covering the design and production of modified plastic pellets and related management activities.

For application-specific projects, WanHan Plastic states that it can provide material selection, formulation adjustment, and processing support based on customer requirements and service conditions. This approach enables its PA66 GF30 portfolio to address different combinations of mechanical, thermal, dimensional, and processing requirements rather than treating the GF30 designation as a single universal material specification.
