Ultrahigh-molecular-weight Polyethylene Porous Film SUNMAP™

Porous film offers air permeability without changing the characteristics of ultrahigh-molecular-weight polyethylene.

"SUNMAP™" is an ultrahigh-molecular-weight polyethylene porous film developed by Nitto Denko's original technology of special calcinations in which ultrahigh-molecular-weight polyethylene powder is formed into a porous sintered compact, then cut. The porous film provides new characteristics such as air permeability and low friction coefficient while maintaining the superior characteristics of ultrahigh-molecular-weight polyethylene such as chemical resistance, abrasion resistance, and releasability. With excellent processability, it offers and will expand a wide range of applications.
