Polyurethane (PU) Roller

Physical Character: Made with high quality polyurethane material by cast. With very good chemic erode resistant, impregnant resistant, ozone resistant, radiation resistant, aging resistant, hydrolyze resistant. And high tear resistant, high impact resistant, high bend strength and low compression set etc. The abrasion resistant is 5 multiple more than pure natural rubber, and the oil resistant is 3-5 multiple more than NBR rubber, and have high elasticity 65% with prominent compression resistant at high temperature. With broad hardness range on 15-98Shore A, very good viscidity with metal material, it is a new macromolecule material with fast evolutive now. Apply to military, mine, oil field, chemical, printing, punch, paper making, Shoe making, spin, auto etc industrial.
