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. Baking EPX 82 in an inert oven significantly improves functional toughness and impact strength while still retaining other key performance metrics.

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.
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.
