Formula: ETFE
Form: Foil/Film/Sheet
Material: Ethylene tetrafluoroethylene (ETFE)
CAS Number: 25038-71-5
Commodity: Polymers
Ultra-high molecular weight polyethylene (UHMWPE) films are highly valued for their exceptional wear resistance, tensile strength, flexibility, and chemical stability, making them suitable for a range of industrial applications. Such films may be used in biomedical devices like hip replacements to reduce wear and enhance longevity. Their low friction and durability also make them ideal for tribological studies, particularly in silicon-based devices. Surface modifications and stretching techniques are applied to improve their strength for use in high-strength composites. Additionally, UHMWPE films are being explored in thermal management and flexible electronics, thanks to their high thermal conductivity and flexibility. These properties make UHMWPE films essential in various industries, particularly in material science, engineering, and technology.
