The following information gives an overview of the benefits of thermosetting plastics and applications and industries which have moved from metal to thermoset materials.


Why should engineering switch from a Metal to a Thermoset material?

Thermoset components offer important benefits over metal counterparts including lower costs, lower weight, resistance to heat and corrosion, and available molded-in tolerances and surface finishes possible.



How do Thermoset components cost less than Metal counterparts?

Thermoset components provide lower tooling costs, part consolidation, and molded-in tolerances which eliminate costly secondary machining processes.


What are industries that have benefitted from Metal-to-Thermoset conversion?

As an early adapter, the automotive industry has been using thermoset components for a variety of under-the-hood applications for some time. More recently, the electrical and lighting industries have enjoyed the use of thermosetting plastics due to superior dielectric strength and thermal insulation while the appliance industry has been drawn in due to higher design flexibility and part consolidation.
