The Application of Polyurethane Wheels in Production Enterprises

DESCRIPTION

The application of polyurethane rubber wheels in production enterprises.


    1. physical and mechanical performance indicators can be adjusted through the choice of raw materials and formulations, polyurethane covered rubber wheels within a certain range of flexible changes, so as to meet the unique requirements of users for the performance of the product. For example, the hardness is often an important indicator of the user's products, polyurethane elastomer can be made into a Shore A hardness of about 20 soft printing rollers, and Shore D hardness of more than 70 hard rolling rollers, which is difficult to do with general elastomer materials, can be suitable for different user needs. Polyurethane elastomer is a polar polymer material composed of many flexible and rigid chain segments. With the increase of the proportion of rigid chain segments and the increase of the density of polar groups, the original strength and hardness of the elastomer will increase accordingly.

 

  2.Superior wear resistance.

  In the working conditions where water, oil and other wetting media exist, the wear resistance of polyurethane covered wheels is often several times to dozens of times that of ordinary rubber materials. Metal materials such as steel are hard but not necessarily wear-resistant; other materials such as rice milling machine rollers, vibrating sieve plates for coal selection, athletic track, dynamic oil seals for cranes and shovels, elevator wheels and roller skates are also useful for polyurethane elastomer.


  3. Diverse processing methods, wide applicability.

  Polyurethane covered wheel elastomer can be used with general-purpose rubber as plastic refining, mixing, vulcanization process; can also be made of liquid rubber, pouring molding or spraying, potting, centrifugal molding (CPU); can also be made of granular material, the same as ordinary plastics, injection, extrusion, calendering, blow molding and other processes (CPU). Molded or injection molded parts, within a certain hardness range, can also be cut, trimmed, drilled and other mechanical processing. The diversity of processing makes the applicability of polyurethane elastomer very wide and the application field is 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 reason why polyurethane covered wheel elastomer is widely used in military, aerospace, acoustics, biology and other fields.
