Polyphenylene sulfide (PPS) is a semicrystalline material. It offers an excellent balance of properties, including high temperature resistance, chemical resistance, flowability, dimensional stability and electrical characteristics. PPS must be filled with fibers and fillers to overcome its inherent brittleness.

Because of its low viscosity, PPS can be molded with high loading of fillers and reinforcements. These fillers and reinforcements will make a difference in the strength, surface properties, dimensional stability, electrical properties and overall cost.

Because of its inherent flame retardancy, PPS is ideal for high temperature electrical applications.
