Thermoset Composites for Electrical Materials

Norplex-Micarta’s thermoset composites for electrical materials have superior creep resistance, dielectric strength, temperature resistance, and mechanical support.

We’ve been making composite materials for our clients in the electrical industry for over 100 years. From our earliest days as composite material designers up to the present day, we’ve seen that thermoset composites deliver as nonelectrically conducting mechanical structures time and time again.

So, what provides our thermoset composites for electrical materials with the characteristics they’re known for? 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. Whether you need your thermoset composites for electrical materials to perform with exceptional durability, in extreme temperatures, exhibit significant strength with minimal weight—or all of the above—we have you covered.

The initial step in our design process is identifying an applicable prepreg. A pre-impregnated material is a resin matrix combined with a reinforcing material or structure. Next, the prepreg is processed into a cured, ready-for-application form, whether that is a specific shape or a sheet.
