Glass Fiber Reinforced PA66 GF30

 30% Glass Fiber Reinforced Nylon 66 for High-Performance Structural Applications

PA66 GF30 is one of the most widely specified high-performance glass fiber reinforced nylons for demanding structural applications. By incorporating 30% chopped glass fiber into the PA66 matrix, this material achieves excellent stiffness, high tensile strength, and superior heat resistance.

Compared with PA6 GF30, PA66 GF30 offers higher melting temperature, better mechanical retention after moisture absorption, and improved long-term thermal stability, making it the preferred choice for automotive and industrial environments.
