Material Overview

EPX 82™ offers outstanding performance in demanding applications. Its heat deflection temperature ranges from 104°C to 130°C (depending on conditioning), making it ideal for automotive and industrial parts requiring high-temperature resistance, stiffness, and impact strength. For enhanced performance, baking EPX 82™ in an inert oven significantly improves its toughness and impact strength without sacrificing other key metrics.

Key Features:

High Strength and Stiffness: Delivers robust mechanical properties similar to glass-filled thermoplastics, providing durability in demanding applications.
Temperature Resistance: Withstands temperatures up to 130°C, ideal for parts exposed to high heat in automotive and industrial settings.
Functional Toughness: Engineered to endure impact and mechanical stress, offering resilience for parts that undergo regular handling and wear.
Enhanced Toughness with Heat Treatment: Heat treatment in an inert oven improves functional toughness and impact strength, ensuring even greater durability.
