About Rubber

Compare over 15 types of rubber to find the right material for you.

High-Strength Buna-N Sheets

Compared to standard Buna-N, this Buna-N is stronger, lasts longer, and absorbs shock better. It resists fuel oil, hydraulic oil, ethylene glycol, and grease. Buna-N is also known as nitrile, NBR, and acrylonitrile butadiene.

Plastic Washers

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.

High-Strength Glass-Filled Nylon—Stronger than plain nylon, but not quite as strong as PEEK. These washers will swell and weaken when exposed to moisture, so they are best for dry environments.

Tear- and Abrasion-Resistant Polyurethane Rubber Sheets

This polyurethane combines the shock absorbing qualities of rubber with the tear resistance of plastic. Use it for high-tension applications such as conveyor belts, as well as for high-wear applications such as cutting surfaces, bumpers, and liners.
