PA66 GF25 Compound is a highly adaptable modified plastic raw material that combines the inherent toughness of nylon 66 with the reinforcing performance of glass fiber. Through advanced modification technology, the material achieves a perfect balance of mechanical strength and processability, eliminating the trade-off between performance and production efficiency. Unlike ordinary nylon 66, PA66+25%GF Pellets maintain excellent structural integrity even in high-temperature working environments, and their superior dimensional stability ensures consistent quality for mass-produced parts. As a cost-efficient alternative to metal, it has become a staple material for automotive, machinery, electronics, and electrical appliance manufacturing, delivering optimal durability and economic efficiency for end products.


High strength and high rigidity with enhanced tensile and flexural performance
Excellent heat resistance for stable operation in high-temperature environments
Halogen-free flame retardant option for environmental and safety compliance
Superior dimensional stability for precise part manufacturing
Outstanding creep resistance for components under continuous mechanical load
Boosts product service life with robust mechanical properties, reducing failure rates
Retains structural and functional integrity in high-heat conditions, expanding application scenarios
Meets global environmental industrial standards, facilitating international market access
Enables the production of high-precision industrial parts with consistent dimensions
Maintains reliable performance for components bearing long-term continuous loads, avoiding deformation
PA66 GF25 Compound gains its competitive edge from professional modification and formula optimization. On the basis of pure nylon 66, the addition of high-quality glass fiber significantly enhances the material’s tensile strength, flexural strength, and overall rigidity, with its fatigue resistance improved by more than 2.5 times compared to unmodified PA66. The Halogen-free FR PA66 GF25 pellets further optimize dimensional stability, solving the problem of part warpage and deformation in processing and use, and ensuring the precision and reliability of finished products. In addition, the material’s high cost-effectiveness makes it a cost-saving choice for enterprises while meeting high-performance requirements, and it supports customized production to match different processing and application needs.
