Polymer - UHMWPE

What are UHMWPE Seals? 

Ultra-High Molecular Weight Polyethylene (UHMWPE) is an extremely durable thermoplastic polymer. As part of the Polyethylene (PE) family, UHMWPE has a high resistance to chemicals, very low moisture absorption, impact strength, excellent abrasion, and wear resistance than other plastic polymers. UHMWPE is commonly used in sealing applications for a variety of industries including oil and gas, life sciences, food and beverage and more.
