Glass Fiber Reinforced PA6 GF20
20% Glass Fiber Reinforced Nylon 6 for Balanced Structural Applications
PA6 GF20 is one of the most widely used glass fiber reinforced nylon materials in structural applications. By incorporating 20% glass fiber, this grade significantly improves stiffness and strength compared to unfilled PA6, while preserving the excellent toughness, fatigue resistance, and wear performance that Nylon 6 is known for.
Compared with higher glass fiber PA6 grades, GF20 delivers a well-balanced mechanical profile, making it ideal for parts that must endure vibration, repeated stress, and mechanical impact without brittle failure.
Material Composition & Glass Fiber Reinforcement Structure
PA6 GF20 is produced using advanced compounding technology to ensure uniform glass fiber dispersion within the Nylon 6 matrix. The reinforced structure enhances load transfer efficiency while retaining polymer chain mobility for impact absorption.
Material Composition Overview
-
Base Polymer: Polyamide 6 (PA6 / Nylon 6)
