PPS Washer

Available Configurations

Properties common to all products in this list

Composition: PPS Form: Washer Material: Polyphenylene sulfide (PPS) Commodity: Polymers
PPS Washer combines high compressive strength, thermal stability, and dielectric insulation in a thin annular format suited for demanding fastening systems. Its ability to maintain integrity under continuous thermal cycling and chemical exposure makes it essential in aerospace, automotive, and power electronics. Applications include electrical insulation spacers, chemical-resistant seals, and load-distributing washers in fastening assemblies. Research explores PPS washers in stress-distribution testing, high-voltage insulation systems, and polymer-metal hybrid joints. Their washer geometry ensures consistent thickness, reliable insulation, and compatibility with standardized fastener sizes. By combining dimensional stability with resistance to creep and hydrolysis, PPS washers serve as reliable components in environments where metallic or lower-grade polymer washers fail, reinforcing their value in advanced industrial systems.
