Ultra-Low-Friction UHMW Polyethylene Sheets

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 plastic can’t. These sheets are often used to make machine guards and chute liners. They are all FDA compliant for direct food contact.

Ultra-Machinable Delrin® Acetal Sheets

These sheets 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.

Ultra-Machinable Acetal Sheets

An economical alternative to Delrin® acetal resin, these acetal copolymer sheets 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.
