Polyphenylene Sulfide

Polyphenylene Sulfide (PPS) is an important and popular polymer because of it’s resistance to heat, acids, alkalis, mildew, bleaches, aging, sunlight, and abrasions. Because of its inherent flame retardancy, PPS is ideal for high temperature electrical applications. Because of its low viscosity, PPS can be molded with high loading of fillers and reinforcements, which is needed to compensate for its inherent brittleness. However, fillers and reinforcements can also increase strength, surface properties, dimensional stability, electrical properties, and overall cost.
