The ultrahigh molecular weight polyethylene sheet is melted and sintered into a billet or a profile under high pressure using a molding or plunger extrusion process, and then subjected to subsequent machining if necessary. Ultra-high molecular weight polyethylene sheets can also be used as modifiers for addition to other compounds to improve their chemical properties. If a vibrating rotary mixer is used, the molten ultra-high molecular weight polyethylene plate can be infiltrated into the inside, so that the amorphous ultra-high molecular weight polyethylene plate can form a complex continuous network structure.
Ultra-high molecular weight polyethylene sheets can be processed into other materials and can be used as additives.
