(1) Excellent wear resistance: wear resistance is the highest among all rubbers. Laboratory measurement results show that the abrasion resistance of UR is 3 to 5 times that of natural rubber, and it is often as high as about 10 times in practical applications.

(2) High strength and good elasticity in the hardness range of Shore A60 to Shore A70.

(3) Good cushioning and shock absorption. At room temperature, the UR shock absorption element can absorb 10%-20% of the vibration energy. The higher the vibration frequency, the greater the energy absorption.

(4) Good oil resistance and chemical resistance. UR has a low affinity with non-polar mineral oils, and is hardly corroded in fuel oils (such as kerosene, gasoline) and mechanical oils (such as hydraulic oil, engine oil, lubricating oil, etc.), and is much better than general rubber. It is comparable to nitrile rubber. The disadvantage is that it has greater swelling properties in alcohols, esters, ketones and aromatic hydrocarbons.

(5) The friction coefficient is relatively high, generally above 0.5.

(6) Low temperature resistance, ozone resistance, radiation resistance, electrical insulation, and good bonding properties.
