Thermoset Composites for Electrical Applications

Outstanding dielectric strength, electrical creep resistance, mechanically strong, temperature resistant

Norplex-Micarta finds its roots in the electrical industry, over 100 years ago. From those early days until now, thermoset composites have proven their value as mechanical structures that do not conduct electricity. 

These properties are derived from the nature of the components in the composite. The two major components are the resin matrix and the reinforcement. By selecting these for the specific application and use conditions, thermoset composites offer a wide design window with the added benefit of affordable mass production.

Norplex-Micarta first produces pre-preg. This material is the combination of a resin matrix and a reinforcement. Pre-preg is then further processed into its final cured form: sheets, or shapes.
