What Are Thermoset Resins?

A thermoset resin is defined as a rigid petrochemical material that requires chemical curing brought on by heat and a catalyst. They are generally made of cross-linking polymers produced by chemical bonding that also allow for extreme resistance to high temperatures. However, low elongation and elasticity upon hardening can occur, plus recycling the resin doesn’t allow for melting or reheating for different shapes.

When heat is applied, its heavy cross-linking structure eliminates the risk of remelting the materia. It is ideal for electronics and appliances since their shape tends to remain dimensionally stable.

Resins are supplied in liquid form to make thermoset resins processable, it often requires other chemicals and not only resins. The impregnation with reinforcing fibers such as fiberglass, Kevlar, or carbon fibers provides them with the required strength and stability.
