PU Polyurethane urethane rubber roller with keyway

Characteristics of polyurethane elastomer: 1. Wear resistance: The wear resistance of polyurethane elastomers is very outstanding, generally about 3-5 times that of natural rubber, and enjoys the reputation of "wear-resistant rubber"; 2. Wide range of hardness: the low hardness range of polyurethane elastomer can be around shore A 10, and the high hardness can reach shore D85; 3. High strength: Under the hardness of rubber, the tensile strength and tear strength of polyurethane elastomer are much higher than that of general rubber; under the hardness of plastic, their impact strength and flexural modulus are much higher than that of plastic; 4. Oil resistance: The oil resistance of polyester polyurethane elastomer is not lower than that of nitrile rubber; 5. High bearing capacity: As polyurethane elastomer can increase the hardness while maintaining rubber elasticity, a higher bearing capacity can be achieved; 6. Low temperature resistance performance: Polyurethane elastomer has good low temperature performance. The brittleness of the containment is generally low (-50℃-60℃). Some formulations have a catalytic temperature lower than -60℃, so polyurethane elastomer products are particularly suitable In a cold environment; 7. Water and mildew resistance: Polyether polyurethane has better water and mildew resistance.
