0.04" Plastic Sheets | McMaster-Carr

Practically nonabsorbent, these sheets, bars, and strips won't swell when exposed to water. They’re harder and denser than LDPE, plus they’re more chemical resistant. They are often machined into plugs, seals, and containers.

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.

Adhesive-back strips are made of Delrin® that is FDA compliant and meets UL 94 HB; however, their adhesive does not meet these specifications.

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 and test report.

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

Dust Covers for Wire Shelving

Nylon

Protect shelved items on all sides—these covers rest over heavy duty wire shelving units to keep out dust. One side opens and closes with hook and loop, so you can quickly access shelves without removing these covers entirely. All have reinforced corners to protect against tearing.

Choose a cover that matches the outside dimensions of your shelving unit, not including the casters. Covers that are too long will get caught in casters or drag on the ground.

Nylon covers have a vinyl coating for outdoor use. They resist UV rays, water, bacteria, odors, mildew, and flames.

Debris Collection Tarps

Pile debris on one of these heavy duty tarps for convenient removal. Also called roofers tear-off tarps, they are waterproof and puncture resistant. Sewn-on strips of cargo webbing add support and steel O-rings at the end of each strip allow secure lifting when attached to a clevis hook (not included).
