Why is PU Caster popular?
2022-11-30
PU casters are commonly known as polyurethane and spring glue, which are all called polyurethane or isocyanate polymers. PU Castor is a kind of elastomer between plastic and rubber, and its comprehensive performance is not possessed by ordinary plastic and rubber. PU wheel has superior shock absorption performance, which can absorb shock and buffer pad, and is more impact resistant than metal spring, without damaging the mold. Advantages of PU Caster: The elastomer of PU Caster has good properties such as wear resistance, chemical corrosion resistance, high strength, high elasticity, low pressure resistance, wear resistance, strong shock absorption, tear resistance, radiation resistance, high bearing capacity, shock absorption and cushioning. PU casters can be molded by plastic refining, mixing and vulcanization processes just like general rubber; It can also be made into liquid, poured and molded or sprayed, sealed and centrifuged; It can also be made into granules, which are molded by injection, extrusion, calendering, blow molding and other processes, just like ordinary plastics. The molded or injection molded parts can also be machined such as cutting, grinding, drilling, etc. within a certain hardness scale. The diversity of processing makes the applicability of PU elastomer very common, and the application scope has been expanding.
