Polyethylene Rod is a solid plastic rod extruded or molded from polyethylene resin. Depending on its molecular weight, common types include:
HDPE Rod (High Density Polyethylene)
UHMW-PE Rod (Ultra High Molecular Weight Polyethylene)
It is widely used in mechanical parts processing, sliding guides, food industry, chemical equipment, electrical insulation, wear-resistant structural parts and other fields.
