The Advantages of Polyurethane Wheels

As a common rubber wheel in daily life, polyurethane coated wheels are widely used in the fields of military industry, aerospace, acoustics, and biology. So what advantages determine that more and more users choose it?

1. Superior wear resistance

In the presence of water, oil and other wetting media, the wear resistance of polyurethane coated wheels 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 vibrating screens, sports ground race tracks, and dynamic oil seals for crane forklifts Rings, elevator wheels, roller skate wheels, etc. are also where polyurethane elastomers come in. 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 and other lubricants can be added to such polyurethane elastomers.

2. Diverse processing methods and wide applicability

Polyurethane rubber-coated wheel elastomers can be molded by plasticizing, mixing, and vulcanizing processes like general rubber, or they can be made into liquid rubber, cast and molded, or sprayed, potted, and centrifuged; they can also be made into pellets, and Like ordinary plastics, it is formed by injection, extrusion, calendering, blow molding and other processes. 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 application fields continue to expand.

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