Thermoset Materials

Thermoset materials are commonly used for electrical insulation, as the materials withstand high temperatures without losing their shape or structural integrity. A chemical reaction takes place during the manufacturing process, creating the permanently-hard nature of the material. Thus, parts made with thermoset plastics  can be fabricated to very tight tolerances.

Thermosets also resist corrosion and mechanical creep.

These plastics are not recyclable because – as their name implies, once heated, the material is set and cannot be remelted for re-forming.

At Dielectric Manufacturing, we use a wide variety of thermoset plastics to fabricate components with great precision. Some of the common thermoplastics we handle are fish paper, glass epoxy (including fire-resistant versions) and glass cloth, canvas and Micarta laminates.
