High-strength, excellent long-term durability, functional toughness

High-Strength, Long-Term Durability, and Functional Toughness

EPX 82 is a high-strength epoxy-based engineering material with excellent long-term durability and mechanical properties comparable to lightly glass-filled thermoplastics (e.g. 20% GF-PBT, 15% GF-Nylon). EPX 82 has a heat deflection temperature ranging from 104°C to 130°C (depending on conditioning) and the functional toughness required for a variety of automotive and industrial applications such as connectors, brackets, and housings.

Chemical Resistant

EPX 82 shows no surface blemishes and minimal change in tensile properties after chemical exposure simulating splash contact per USCAR-2 conditions.

Exceptional Endurance

EPX 82 has excellent retention of material properties during high temperature aging, temperature/humidity cycling, and thermal shock.

Low Off-Gassing

EPX 82 passes stringent odor, fogging, and emissions standards required for interior automotive applications.

Full Case Study

Example Applications

These applications combine a need for functional toughness, stiffness, and temperature resistance, in addition to isotropy, great surface finish, and accuracy.

CONNECTORS

This T2 connector requires toughness, stiffness, temperature resistance, chemical resistance, accuracy, and surface finish.

BRACKETS

Demanding brackets often require toughness, stiffness, temperature resistance, accuracy, and occasionally chemical resistance.

HOUSINGS

Housings, especially in consumer facing parts, require toughness, stiffness, temperature resistance, accuracy, and a great surface finish.
