Ultra-Low-Friction UHMW Polyethylene Bars

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 bars are often used to make machine guards and chute liners. They are all FDA compliant for direct food contact.

Oil-Filled UHMW Polyethylene Rods

Often used as rollers, these oil-filled UHMW rods are self-lubricating for an extra-slippery surface that resists wear. They also offer excellent impact resistance.
