Using Thermosets in High Temperature Applications
Comments Off on Using Thermosets in High Temperature Applications
Thermosets are used in molding applications requiring an end-part or product assembly to remain dimensionally stable within challenging and aggressive environments. One of the main benefits of using a thermoset in a molded application is thermosets’ heat resistance and high deflection temperatures that allow the molded components to exhibit excellent dimensional stability, durability, strength, and creep resistance while exposed to elevated operating temperatures. Thermoset materials offer heat resistance up to 400F-500F continuous operating temperatures, depending on the material formulation, whereas thermoplastic molding materials such as a nylon or ABS may melt or disfigure, jeopardizing the integrity of the product or assembly.

Why are thermoset composites like phenolic and bulk molding compound commonly used material in automotive applications? Molded thermoset parts and components have excellent material properties with regards to resistance against high temperatures, corrosion, and chemicals and automotive fluids. Processing wise, thermosets may be injection molded, or compression molded.
