HDPE (High Density Polyethylene) sheets are extremely resistant to impact, abrasion, and friction. These moisture, stain, and odor resistant polyethylene sheets are used in the food processing industry. Impact-resistant acrylic sheets can be used in a variety of applications, including picture framing, skylights, displays, signage, and lighting applications. High-impact polycarbonate sheets can be used in security and injection molding applications. Many lenses and compact discs are made of polycarbonates. Zoro also has a great selection of UHMW polythylene sheets, polypropylene sheets, and PVC/acrylic sheets too.
