Chemicals group completes production expansion for ultra-high molecular weight polyethylene

Mitsui Chemicals, Inc. has expanded production facilities to manufacture HI-ZEX MILLION™ ultra-high molecular weight polyethylene in response to growing demand for automotive and industrial batteries. The additional facilities came online on August 7.

This action boosts the company's production capacity for HI-ZEX MILLION™ by about 15% to 8,500 tons per year.

Mitsui Chemicals developed HI-ZEX MILLION™ through the application of the company’s proprietary technology in catalysts and processes, giving this ultra-high molecular weight polyethylene an average molecular weight of 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™ retains a consistent shape and provides excellent solubility. With these properties helping to streamline customers' fabrication processes, the product has been certificated Mitsui Chemical's Blue Value™*.

Positioning HI-ZEX MILLION™ as a strategic product in the key business domain of mobility, Mitsui Chemicals will continue to be proactive in further strengthening and expanding this business.
