Primef® polyphenylene sulfide
Primef polyphenylene sulfide* (PPS) is a highly fluid plastic that is inherently flame retardant. Components molded from Primef compounds offer excellent dimensional stability and have virtually no water absorption. They are unaffected by an impressive range of organic and mineral-based chemicals, even at high temperature over a prolonged period of time. These attributes combined with a continuous use temperature up to 428°F (220°C) make Primef resins a reliable choice for demanding applications in automotive, coatings, electrical, electronics and the chemical processing industry.
