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.

Clear Machinable Cast Acrylic Sheets

These cast acrylic sheets are often fabricated into tanks, see-through barrier panels, and light fixture lenses. Cast acrylic, which is comparable to Lucite and Plexiglas® acrylic, is easier to machine than extruded acrylic. The material is scratch resistant and stands up to outdoor use better than polycarbonate. It maintains clarity over time and won't weaken from exposure to UV, though the pigment in colored acrylic will fade over time when exposed to direct sunlight.
