The Advantages of Polyurethane Castors
The elastomer of polyurethane casters has good properties such as wear resistance, chemical resistance, high strength, high elasticity, low pressure resistance, strong shock absorption, tear resistance, radiation resistance, high load bearing and shock absorption. Polyurethane wheels have excellent sound-absorbing characteristics, and the wheels do not produce noise during movement, which can achieve a quiet effect. These characteristics of PU wheels are very suitable as caster materials.
1. The performance can be adjusted in a large range
A number of 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.
2. 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 ordinary rubber materials. Although metal materials such as steel are very hard, they are not necessarily wear-resistant.
3. Various processing methods and wide applicability
Polyurethane elastomers can be molded, mixed, and vulcanized like general-purpose rubber (referred to as MPU); they can also be made into liquid rubber, poured and molded or sprayed, potted, and centrifugally formed (referred to as CPU); Pellets, like ordinary plastics, are formed by injection, extrusion, calendering, blow molding and other processes (referring to CPU). Molded or injection-molded parts can also be machined for cutting, grinding, drilling, etc. within a certain hardness range.
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 why polyurethane elastomers are widely used in military, aerospace, acoustics, biology and other fields.
