1. The physical and mechanical performance indicators can be flexibly changed within a certain range through the selection of raw materials and the adjustment of formula, so as to meet the unique requirements of users for product performance. For example, hardness is often an important indicator of the user's products, polyurethane elastomers can be made into soft printing rubber rolls with a hardness of about 20 in Shaw A, and can also be made into hard rolled steel rolls with a hardness of more than 70 in Shaw D, which 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 chain segments, and the original strength and hardness of the elastomer will increase accordingly with the increase of the proportion of rigid chain segments and the increase of polar group density.

2. Superior wear resistance.

Under the working conditions of water, oil and other wetting media, the wear resistance of polyurethane rubber wheels is often several times to dozens of times that of ordinary rubber materials. Although metal materials such as steel are very hard, they are not necessarily wear-resistant; Other such as glue rollers for rice milling, vibrating screens for coal preparation, track tracks for sports fields, dynamic oil seals for cranes and forklifts, elevator wheels and roller skate wheels, etc. are also places where polyurethane elastomers are used.

3. Various processing methods and wide applicability.

Polyurethane rubber wheel elastomers can be molded by plastic, compounding and vulcanization processes like general rubber; It can also be made into liquid rubber, pour molding or spraying, potting, centrifugal molding (referring to CPU); It can also be made into granules, which can be molded by injection, extrusion, calendering, blow molding and other processes (referring to CPU) like ordinary plastics. Molded or injection-molded parts can also be machined such as cutting, grinding, and drilling within a certain hardness range. The diversity of processing makes polyurethane elastomers widely applicable and the fields of application are constantly expanding.

4. Oil resistance, ozone resistance, aging resistance, radiation resistance, low temperature resistance, good sound transmission, strong adhesion, excellent biocompatibility and blood compatibility. These advantages are the reasons why polyurethane coated wheel elastomers are widely used in military industry, aerospace, acoustics, biology and other fields
