Dureflex X2133 is a highly elastic aromatic polyester polyurethane used in films and sheets. It is reportedly stronger than rubber and resists petrochemicals such as gasoline, diesel fuel, aviation fuel, and many solvents. It has a hydrolytic stabilizer and withstands long-term exposure to water and high humidity better than standard polyester TPUs. X2133 can be formulated with lubricant and slip packages to provide various combinations of surface slip and product haze. It can be supplied in its natural color or be pigmented.
