UHMWPE Rod

Formula: UHMWPE, HMPE, HPPE

Form: Rod

Material: Ultra-high-molecular-weight polyethylene (UHMWPE, HMPE)

CAS Number: 9002-88-4

Commodity: Polymers

UHMWPE Rods are high-performance engineering plastic rods we produce within our extensive range of polymer products. With 97 size variations available, they provide outstanding abrasion and chemical resistance, impact strength and a low coefficient of friction. Commonly used in demanding applications where high wear resistance is required, these rods offer superior performance for parts in mining equipment, conveyor systems and food processing machinery. The exceptional toughness and durability of our UHMWPE Rods make them ideal for replacing metal parts vulnerable to corrosion and fatigue.
