Valley Roller’s Polar-Rite™ Series of roll coverings offer a superior balance of chemical resistance and heat resistance properties to alternative roll coverings. Polar-Rite™ coverings have a saturated polymer backbone, which accounts for excellent heat resistance, up to 350°F continuous exposure. Polar-Rite™ is based upon a “non-polar” type polymer, and thus exhibits great
resistance to “polar” solvents such as ketones and esters. Polar-Rite™ coverings offer a balance of physical properties that make this family of coverings an excellent choice for many coatings and general industrial roll applications. Polar-Rite™ coverings are available in wide range of hardness from 30 - 95 Shore A.
