About glass-filled nylon

Adding glass fiber to nylon multiplies its stiffness and strength and lifts its heat deflection temperature dramatically, which is why PA66 GF30 and PA6 GF30 are among the most-used engineering compounds in the world. PA66 gives more heat resistance; PA6 gives a better surface finish and is a little easier to process. Specs usually call out the base resin, glass percentage and additive package (heat stabilized, impact modified, hydrolysis resistant, lubricated, flame retardant). Send us yours and we’ll match it.
