PPS (Polyphenylene Sulfide) is a tough, high-performance engineering thermoplastic featuring high dimensional stability.

Regulatory: ASTM/Mil-Spec, FDA


PPS (Polyphenylene Sulfide) is a tough, high-performance engineering thermoplastic featuring high dimensional stability. It combines good mechanical properties with excellent thermal resistance, and offers the broadest chemical resistance of any engineering plastic. There are no known solvents of PPS below 392° F (200° C).

PPS is produced in compression molded and extruded forms, with differentiated properties for each. It also can be processed with fillers, resulting in a wide range of grades including glass/mineral filled, conductive and anti-static grades, internally lubricated bearing grades and FDA compliant grades for your food processing machinery needs.

Polymershapes can meet your PPS needs with sheets and rods in a variety of dimensions, from leading edge suppliers including Quadrant Engineering Plastics, makers of Techtron®. We have the material you need in standard and custom sizes – whatever your PPS requirements, you can rely on Polymershapes to deliver the length, width and thickness you need to meet your most demanding projects.
