Grade: Ultra-High Molecular Weight (UHMWPE)
Formula: UHMWPE, HMPE, HPPE
Form: Foil/Film/Sheet
Material: Polyethylene (PE)
CAS Number: 9002-88-4
Commodity: Polymers
UHMWPE Film combines the outstanding strength, impact resistance, and low friction of ultra-high molecular weight polyethylene in a thin, flexible form. Known for excellent wear and chemical resistance, this film is widely applied in protective barriers, biomedical devices, and tribological research. Industries including medical technology, defense, and chemical engineering use UHMWPE films for protective coatings, implantable medical components, and chemically inert liners. Specific applications include biocompatible membranes in drug delivery devices, protective films in defense armor composites, and friction-reducing layers in mechanical systems. In research, UHMWPE films are studied for their fatigue resistance, surface modification for adhesion, and cross-linking techniques to improve durability. Their combination of flexibility, chemical stability, and bio-inertness makes UHMWPE films critical for next-generation biomedical and industrial applications requiring lightweight but highly durable polymeric materials.
