The application of polyurethane rubber wheels in production enterprises:

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 for users of products. Polyurethane elastomers can be made into soft printing rubber rollers with Shore A hardness of about 20, and hard steel rolling rubber rollers with Shore D hardness of more than 70. This is difficult for general elastomer materials, and can be adapted to the needs of different users. Polyurethane elastomer is a polar polymer material composed of many flexible segments and rigid segments. As the ratio 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 the working conditions in the presence of wetting media such as water and oil, the wear resistance of polyurethane rubber-coated wheels is often several to dozens 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 rubber rollers for rice milling machines, vibrating screen plates for coal preparation, track race tracks in sports fields, dynamic oil seals for cranes and forklifts Loops, elevator wheels, and roller skate wheels are also places where polyurethane elastomers come in handy.

3. Various processing methods and wide applicability.

Polyurethane rubber-coated wheel elastomers can be formed by plasticizing, mixing and vulcanization processes like general rubber; they can also be made into liquid rubber, cast and molded or sprayed, potted, and centrifugally formed (referring to CPU); they can also be made into Granules, like ordinary plastics, are formed by processes such as injection, extrusion, calendering, and blow molding (referring to CPU). Molded or injection molded parts can also be processed by cutting, grinding, drilling and other machining within a certain hardness range. The diversity of processing makes the applicability of polyurethane elastomers very wide, and the application fields 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 reason why polyurethane rubber-coated wheel elastomers are widely used in military, aerospace, acoustics, biology and other fields
