Steel lined polyurethane pipe Features: 1, Excellent wear resistance: wear resistance of steel lined polyurethane pipe is excellent, usually about 3~5 times of natural rubber. 2, Wide range of hardness: Low hardness range of polyurethane elastomer is about 10 shore A, high hardness up to shore D85. 3, High strength: In the rubber hardness, tensile strength and tear strength of polyurethane elastomer is much higher than the general rubber; under plastic hardness, their impact strength and flexural modulus is much higher than plastic. 4, Oil resistance: Oil resistance of the polyurethane elastomer is not less than nitrile rubber and relative with polysulfide rubber. 5, High bearing capacity: Polyurethane elastomer can be improved under the premise of maintaining the hardness of rubber elasticity, so as to achieve a high capacity, which is the other rubber can not be compared
