1. Large adjustable range of performance
A number of physical and mechanical performance indicators can be flexibly changed within a certain range through the selection of raw materials and the adjustment of formulas, so as to meet the unique requirements of users for product performance. For example, hardness is often an important indicator of users' products. Polyurethane elastomers can be made into soft printing rubber rollers with a Shore A hardness of about 20, and hard steel rollers with a Shore D hardness of 70 or more. It is difficult to achieve with general elastomer materials and can be adapted to the needs of different users. Polyurethane elastomer is a polar polymer material composed of many flexible and rigid segments. As the proportion of rigid segments increases and the density of polar groups increases, the original strength and hardness of the elastomer will increase accordingly.

2. Superior wear resistance

Under working conditions in the presence of wetting media such as water and oil, the wear resistance of polyurethane tires is often several to several tens of times that of ordinary rubber materials. Although metal materials such as steel are very hard, they are not necessarily wear-resistant; others such as rice hulling machine rubber rollers, coal preparation screens, race tracks in sports fields, and dynamic oil seals for cranes and forklifts. Rings, elevator wheels, roller skate wheels, etc. are also where polyurethane elastomers come in. One point that needs to be mentioned here is that to increase the friction coefficient of low- and medium-hardness polyurethane elastomer parts and improve the wear resistance under load, a small amount of aluminum disulfide, graphite or silicone oil can be added to this type of polyurethane elastomer as lubricant.

3. Diverse processing methods and wide applicability

Polyurethane elastomer can be formed by plasticizing, mixing, and vulcanizing process like general rubber (MPU); it can also be made into liquid rubber, casting molding compression molding or spraying, potting, centrifugal molding (CPU); it can also be manufactured Granular materials, like ordinary plastics, are molded by injection, extrusion, calendering, blow molding and other processes (CPU). Molded or injection molded parts can also be processed by cutting, grinding, drilling and other mechanical processing within a certain hardness range. The diversity of processing makes the applicability of polyurethane elastomers very wide, and the fields of application continue to expand.

4. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound permeability, strong adhesion, excellent biocompatibility and blood compatibility.

These advantages are the reasons why polyurethane elastomers are widely used in military industry, aerospace, acoustics, biology and other fields.
