PA66 GF30

PA66 GF30 is a glass-fiber-reinforced nylon material that combines a polyamide 66 base with 30% glass fiber reinforcement. The glass fiber loading significantly increases stiffness, tensile strength, and load-bearing capability over unreinforced PA66, while reducing creep and deformation under sustained load. Ready Plastics stocks PA66 GF30 for precision machining into structural components, load-bearing brackets, housings, and mechanical elements where dimensional stability under stress is critical.

The 30% glass fiber reinforcement reduces the coefficient of thermal expansion relative to neat PA66, helping components maintain dimensional accuracy across temperature cycles. Rigidity is substantially improved — PA66 GF30 material resists bending and deflection under load more effectively than the base resin, making it appropriate for demanding mechanical environments where unreinforced nylon would deform unacceptably.

Machining considerations. Glass fiber reinforcement makes PA66 GF30 more abrasive to cutting tools than unfilled nylon. Carbide tooling is recommended for extended tool life, and dust extraction is advisable when machining this material. Despite the increased abrasiveness, the material holds acceptable tolerances for structural components and housings.
