About Plastic

About Composites

In addition to having a low-friction surface that prevents sticking and binding, this tough, impact- and wear-resistant material handles the scuffs, scrapes, and strikes that other plastics can’t. These sheets, bars, and strips are often used to make machine guards and chute liners. They are all FDA compliant for direct food contact.

Moisture-Resistant Polyethylene
(HDPE) Sheets, Bars, and Strips

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.

An economical alternative to Delrin® acetal resin, these acetal copolymer sheets and bars offer the same naturally slippery surface and similar wear resistance. They resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. Use them for parts that require precision, such as gears, bearings, and bushings.

In addition to being easier to machine than standard nylon 6/6, these cast nylon 6 sheets and bars are also better electrical insulators. They have a wear-resistant, slippery surface that reduces friction. Use them to make gears, sprockets, and wear strips. This material is comparable to Nylatron and Nycast.

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.
