What are the characteristics of TPU, TPE and TPR caster materials?

If there is demand, there will be innovation. With the intensification of market economic demand, more and more caster materials are coming to everyone's field of vision; although the caster materials are getting richer from time to time, it is very beneficial to think about it, because everyone's choice is strong. , but the advantages and disadvantages are mutually existing, although the selectivity is strong, but so many types, manufacturers, brands, models, and performance also bring us great convenience to choose a good caster! As a qualified purchaser of caster raw materials, you must first have a sufficient understanding of the raw materials, so that you can distinguish the good from the bad. Now we are going to tell you about the characteristics of the three commonly used caster materials, so that you can buy them in the future.

TPU caster material characteristics: wear-resistant TPU, oil resistance, excellent elasticity, good load-bearing capacity, loud noise during operation, long service life, suitable for luggage wheels and various industrial casters, but TPU is not resistant to hydrolysis.

TPE caster material is a kind of material with high elasticity, high strength and high resilience of rubber, and also has the characteristics of injection molding. It is environmentally friendly, non-toxic and safe, has a wide range of hardness, good colorability, soft touch, weather resistance, fatigue resistance and temperature resistance, excellent processing performance, no need for vulcanization, can be recycled to reduce costs, and can be used for secondary injection molding. , It can be coated and bonded with PP, PE, PC, PS, ABS and other matrix materials, and can also be formed separately.

TPE caster material characteristics: excellent wear resistance, elasticity, shock absorption and low noise performance, excellent adhesion with hard plastics, environmental protection and non-toxic; excellent load-bearing, can be molded with PA, PP hard plastics.

Suitable for luggage wheels, trolley wheels and other industries.
TPR caster material characteristics: In a sense, TPR is TPE (polystyrene elastomer category). Its advantages are similar to TPE, but TPR and therefore SBS are the main substrate, which is better than TPE in elasticity, but not better than TPE in wear resistance, and TPR has a lower cost than TPE, and it can also be molded with PA and PP hard plastics.

Suitable for heavy duty casters, industrial casters, etc.

TPU, TPE, TPR are the most common caster materials at present, and there are many brands and manufacturers on the market for these three materials, which also brings a lot to everyone. convenient. And when we choose these, in addition to understanding its own characteristics, we also need to judge according to the needs you want; because choosing it itself is to determine the needs for understanding!
