Plastic Material Selection

The exact plastic material composition is an important factor when specifying parts for equipment used in the lumber and timber industry. Our plastic experts will determine the best plastic material, including custom resins and colors, for your application.

For example, DPI’s UHMW (ultra high molecular weight) polyethylene is an excellent material choice for parts and components used in lumber and timber industry equipment applications that require superior durability, wear resistance, low friction, and corrosion resistance. Additionally UHMW plastic can be machined, fabricated, or injection molded.
