About Washers
More
Plastic Washers
These plastic washers are good electrical insulators.
Nylon washers are stronger than polycarbonate and UHMW washers. Exposure to moisture may cause them to expand. Lubricant-filled nylon washers have a slippery surface that resists wear in high-friction applications.
Polycarbonate washers are more rigid than most plastic washers for high impact resistance. They have good moisture resistance and withstand oil, greases, and detergents.
UHMW washers have excellent moisture and abrasion resistance and good resistance to chemicals.
