The Advantages of Polyurethane Casters

The Advantages of Polyurethane Casters

Excellent wear resistance

Under the working conditions of wet media such as water and oil, the wear resistance of polyurethane casters is often several to dozens of times that of general rubber materials. Although metal materials such as steel are very strong, they are not necessarily wear-resistant; others such as rice huller rubber rollers for rice milling, vibrating sieve plates for coal preparation, track tracks for sports fields, and dynamic oil seals for cranes and forklifts. Rings, elevator wheels and roller skate wheels, etc. are also where polyurethane elastomers come in handy. The staff of polyurethane covered wheels understand that what needs to be mentioned here is that in order to improve the friction coefficient of medium and low hardness polyurethane elastomer components and improve the wear resistance under load, a small amount can be added to this type of polyurethane elastomer. Lubricants such as aluminum disulfide, graphite or silicone oil.

Various processing methods and wide applicability

Polyurethane elastomers can be formed by mastication, mixing, and vulcanization in the same way as general-purpose rubber (referring to MPU); they can also be made into liquid rubber, pouring molding or spraying, potting, and centrifugal molding (referring to CPU); Pellets, like ordinary plastics, are formed by injection, extrusion, calendering, blow molding and other processes (referring to CPU). Molded or injection-shaped parts can also be machined for cutting, grinding, drilling, etc. within a certain hardness range. The diversity of processing of polyurethane rubberized wheels makes the applicability of polyurethane elastomers very wide, and the application fields continue to expand.
