Polyurethane Sheet And Related Products Made By Polyurethane
Our company supply various of Polyurethane plates, also can mold and design related goods according to your request, except Polyurethane plates, we also have Polyurethane conveyor belt scraper,flotation machines rotor, Polyurethane shaft, and hydro cyclone.
Polyurethane has the advantages of high hardness, good strength, high elasticity, high abrasion resistance, tear resistance, aging resistance, ozone resistance, radiation resistance and good electrical conductivity.
(1)The highest wear resistance among all rubbers. Laboratory measurement results show that the polyurethane abrasion resistance is 3 to 5 times of natural rubber, and it is often 10 times high in actual applications.
(2) High strength and good elasticity within Shore A60 and Shore A70 hardness range .
(3) Good cushioning and shock absorption. The shock-absorbing element can absorb 10%~20% of the vibration energy at room temperature. The higher vibration frequency, and greater the energy absorption.
(4) Good oil resistance and chemical resistance. Polyurethane products have low affinity with non-polar mineral oils, and are hardly corroded in fuel oils (such as kerosene, gasoline) and mechanical oils (such as hydraulic oil, engine oil, lubricating oil, etc.), and are much better than general rubber , Comparable to nitrile. The disadvantage of it is having greater swelling in alcohols, esters, ketones and aromatic hydrocarbons.
(5) The friction coefficient is relatively high, generally above 0.5.
(6) Low temperature resistance, ozone resistance, electrical insulation, and good bonding performance.
