Glass Fibre Reinforced Nylon (PA6 GF30): A Buyer's Guide
Adding 30% glass fibre to PA6 nylon can double its tensile strength - here's what that means for your part design and material cost.
What Is PA6 GF30?
PA6 GF30 is nylon 6 compounded with 30% chopped glass fibre by weight. The glass fibre reinforcement significantly increases tensile strength, stiffness and heat deflection temperature compared to unfilled nylon, making it suitable for structural and under-the-hood applications.
Key Property Improvements
Compared to base PA6, the GF30 grade typically shows a large jump in tensile strength and flexural modulus, better creep resistance under sustained load, and a higher heat deflection temperature - useful for parts near engine bays or in continuous mechanical stress.
Processing Considerations
Glass-filled nylon requires higher injection pressures and can be more abrasive on tooling and screws than unfilled resin. Moisture control is critical since PA6 is hygroscopic; the resin must be properly dried before processing to avoid hydrolysis and surface defects.
Typical Applications
PA6 GF30 compounds are used in automotive brackets and housings, electrical connectors, pump components, gears, and industrial equipment parts where metal replacement is the goal without sacrificing structural performance.
