All of these washers are lightweight, nonconductive, and naturally rust resistant. They are commonly used in electronics and automation applications to take the pressure off screws and nuts and protect mounting surfaces.
Extreme-Temperature Polyimide—Our most temperature-resilient plastic washers. These won't deform or lose strength at temperatures as low as -450° F and as high as 750° F to handle everything from liquid nitrogen to heating elements. They are also good electrical insulators.
