Product Information

Teijin has realized a high-performance membrane with highly precise pore diameter and thickness, by merging the basic technologies of gel extrusion and biaxial stretching of ultra-high-molecular-weight polyethylene (UHMWPE) with membrane fabrication expertise, developed by Teijin through many years of experience in various fields.
Miraim combines extreme thinness and high porosity with the strength and chemical resistance of UHMWPE. Besides single monolayer use, it can therefore achieve high fillability of fine particles and high resin impregnability, giving it wide application to use as a supporting material for various functional materials. Moreover, by combining Teijin's technology for microporous membrane formation through phase separation with simultaneous double-sided coating, membranes can be equipped with multiple functions.
