About Plastic

Compare over 25 types of plastic to find the right material for you.

Slippery UHMW Polyethylene Sheets, Bars, and Strips

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.

If you don't see the size of white sheet you're looking for, please specify length and width under additional white sheet sizes.

Clear Scratch- and UV-Resistant Cast Acrylic Sheets, Bars, and Cubes

These cast acrylic sheets, bars, and cubes 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.
