Thermoset Molding Compounds

Thermoset Materials

A thermoset material is made of polymer resins that are cured through a heat and chemical cross-linking process. This curing process transforms the resin into its final form. Once the cross-linking has taken place, the material cannot be melted or re-shaped. Thermoset materials are generally stronger than thermoplastic materials and are better suited to high-temperature and high-strength applications. Thermoset materials are an excellent candidate for products being considered for metal replacement.

Why Choose a Thermoset Material?

Thermoset composite materials are an ideal choice when choosing a material for a product that needs the following properties:

  • Dimensional stability
  • High heat resistance
  • Electrical insulation
  • High flex strength
  • Thermal insulation
  • Corrosion resistance
  • Creep resistance
  • Low fluid absorption

What Are the Applications of Thermoset Material?

Typical applications for these materials are:

  • Electrical enclosures, toggle bars, levers, switch bases, spacers and slip rings
  • Automotive caps and housings
  • Shower and bath fixtures
  • Small and large appliance handles, control panels, side and end panels
  • Outdoor grill shelves and control knobs
  • Lighting luminaires, bases and covers
