Widely used as a protective barrier against abrasion and wear, this UHMW film has a slippery surface that prevents sticking. This film is skived, so the edges may curl.

For adhesive-back film that is FDA compliant, the film meets the standard, but the adhesive does not.

Wear-Resistant Easy-to-Machine Delrin® Acetal Resin Sheets, Bars, and Strips

These sheets, bars, and strips resist expanding when exposed to heat and moisture, so they can be easily machined to close tolerances. They also have a naturally slippery, wear-resistant surface. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

White sheets, bars, and strips are FDA compliant for contact with food.

Slippery Wear-Resistant Easy-to-Machine
Delrin® Acetal AF Resin Sheets and Strips

The addition of PTFE provides a more slippery, wear-resistant surface than standard Delrin® acetal resin. These sheets and strips resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. Fabricate them into pump components, gears, and bearings. Delrin® acetal resin is also known as acetal homopolymer.

Multipurpose Flame-Retardant Garolite G-10/FR4 Sheets and Bars

A good all-around choice, these Garolite G-10/FR4 sheets and bars are strong, machinable, and electrically insulating. They're made of a flame-retardant epoxy resin with fiberglass fabric reinforcement. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.

Wear-resistant sheets are coated to stand up to rubbing and scraping better than uncoated sheets.

If you don't see the size you're looking for, please specify a length under additional bar lengths.

Shim Stock

Cut it into custom shapes to fit your application. Sheets come flat packed.

For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment. Metal shims include a material certificate with traceable lot number. Most shims include a test report.

PTFE plastic shim stock is slippery, so it can be used to reduce friction between parts. It also has excellent chemical resistance.
