Thermoset Plastics

Thermoset Materials

Thermoset materials are commonly used for electrical insulation, or for components used in extreme environments. Thermoset plastics 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. Thermoset plastics are generally stronger than thermoplastic materials.

Parts made via thermoset manufacturing can be fabricated to very tight tolerances. Thermoset parts resist mechanical creep and corrosion.

In some cases, thermosetting polymers can be a lower-cost option to metal for precision parts.

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

Wide Variety of Thermoset Polymers

At Dielectric Manufacturing, we use a wide variety of thermoset polymers to fabricate components with great precision.

Some of the common thermosets we handle are fish paper, glass epoxy (including fire-resistant versions) and glass cloth phenolics, canvas and Micarta laminates, and polyurethanes.
