Introduction
UPE sheet, also known as ultra-high molecular weight polyethylene sheet, is a high-performance engineering plastic sheet made primarily from ultra-high molecular weight polyethylene (UHMWPE). Ultra high molecular weight polyethylene is a thermoplastic engineering plastic with excellent comprehensive properties and a linear structure. Its molecular weight is usually above 1.5 million, and can even reach around 10 million. This high molecular weight property endows UPE sheets with many unique properties.
From the perspective of molecular structure, ultra-high molecular weight polyethylene molecular chains are highly entangled, which increases the sliding resistance between molecular chains, thereby endowing the material with excellent wear resistance, impact resistance, and self-lubricating properties. During the polymerization process, advanced catalysts and polymerization techniques are used to precisely control the molecular weight and molecular weight distribution, in or…
