Polyurethane Rubber Roller

Bestry’s polyurethane rubber roller is synthesized by castable polyurethane with our own technology. Its chain is extended with MOCA, and then it is cast into the mold and vulcanized. Our products are featured with high hardness, high strength, high wear resistance, cutting resistance, good elasticity, tear resistance, impact resistance, compression resistance, oil resistance, alkali resistance, weak acid resistance, anti-aging, good dynamic performance, and easy process operation. These rubber rollers are featured with different high performance, such as wear-resistant and cutting-resistant rubber rollers (granulator rubber rollers), wear-resistant rubber rollers with good dynamic perforance, and wear-resistant rubber rollers with good elasticity.
