Flame Retardant

EPX 86FR passes UL 94 V-0 @ 2 mm and FAR 25.853(a) Vertical Burn @ 1 mm with flame-retardant and self-extinguishing features. EPX 86FR is BlueCard certified.

Thermal Endurance

EPX 86FR is heat resistant with an HDT of 135°C and excellent retention of material properties during high-temperature aging, temperature/humidity cycling, and thermal shock.

Chemical Resistance

EPX 86FR shows no surface blemishes and minimal change in tensile properties after chemical exposure simulating splash contact per USCAR-2 conditions.

Example Applications

These applications combine a need for flame-retardance, functional toughness, and temperature endurance, in addition to isotropy, smooth surface finish, and accuracy.

An open cable clip with wires

Cable Clips

Cable clips for consumer electronics and automobiles require flame-retardance, toughness, stiffness, temperature resistance, accuracy, and occasionally chemical resistance.

T2 Connectors

High-speed Data Connectors

This T2 connector for automobiles requires UL 94 V-0 rating, thermal endurance, chemical resistance, high accuracy and functional toughness.


Housings and Brackets

Demanding housings and brackets for electronics often requires flame-retardance, stiffness, temperature resistance, accuracy, and a great surface finish.
