Mitsui Chemicals Hi-Zex Million UHMWPE possesses and average molecular weight of 0.5 million up to 6 million. Due to the material's excellent chemical resistance, abrasion resistance, impact resistance and self-lubrication, it is used in diverse fields such as lithium-ion battery separators, industrial materials and medical devices. Furthermore, Hi-Zex Million UHMWPE reportedly retains a consistent shape and provides excellent solubility.
