TPU caster characteristics: TPU is highest wear resistance, oil resistance, excellent elasticity, good load capacity, high noise when running, longest service life, practical for luggage wheels and various industrial casters, but TPU is not resistant to hydrolysis.

TPE caster is a material with high elasticity, high strength, high resilience and the characteristics of injection molding. It has environmental protection, non-toxic safety, wide hardness range, excellent coloring property, soft touch, weather resistance, fatigue resistance and temperature resistance. It has excellent processing performance, no need for vulcanization, and can be recycled to reduce costs. It can be used for Secondary Injection Molding. It can be coated with a base material such as PP, PE, PC, PS or ABS, or it can be molded separately. TPE caster characteristics: excellent wear resistance, elasticity, shock absorption and low noise performance, excellent adhesion with hard plastic, environmentally friendly and non-toxic; excellent load-bearing, can be molded with PA, PP hard plastic.

TPR caster characteristics: In a sense, TPR is TPE, but TPR is therefore SBS-based substrate, which is better than TPE, but its wear resistance is not better than TPE. TPR cost is lower than TPE, it can also be molded with PA, PP hard plastic. It is used for heavy duty casters,And medical casters

TPU, TPE, TPR three kinds of casters are currently the most common caster raw materials, and for these three kinds of raw materials, there are many brands and manufacturers in the market, which also caused great inconvenience to user. When we choose these, in addition to understanding its own characteristics, we must judge according to our needs; because it is chosen to solve the demand!
