Superior wear resistance. Especially in the presence of water, oil and other wet media working conditions, its wear resistance is often several times to several times the ordinary rubber material.

Superior wear resistance.Especially in the presence of water, oil and other wet media working conditions, its wear resistance is often several times to several times the ordinary rubber material. Although metal materials such as steel are very hard, they are not necessarily wear-resistant. For example, in the large water pump in the Yellow River irrigation area, the metal mouth ring and protective ring of its flow-through components are washed by a large amount of sediment, and it takes less than a few hundred hours to seriously wear and leak water, while the mouth ring and protective ring coated with polyurethane elastomer are continuously operated 1800 small and still not worn. Other such as rice hulling machine rollers for rice milling, vibrating screen plates for coal preparation, track tracks in sports fields, dynamic oil sealing rings for crane forklifts, elevator wheels and roller skate wheels are also used for polyurethane elastomers. One point to be mentioned here is that in order to improve the friction coefficient of medium and low hardness polyurethane elastomer parts and improve the wear resistance under load, a small amount of lubricants such as aluminum sulfide, graphite or silicone oil can be added to this type of polyurethane elastomer.
