Jan 30 , 2018Recently, A new customer placed an order Caster Wheel from us but he know little about caster wheel. Therefore we recommended him the right caster material according to his requirements and our professional experiences.
The most common caster wheel materials in the market are TPE, TPR, TPU. Here let’s talk about their advantages and disadvantages and you will have better understanding on how to choose TPE, TPR , TPU caster materials.
1. TPE material: TPE is environmentally and non-toxic material, with features of excellent wear resistance, elasticity, shock resistance and low noise performance. As it has good adhesion property with hard plastic. It can be coated and formed with hard plastic like PA,PP. TPE material is with great load capacity. Currently, TPE material is widely used for luggage caster,cart caster and industrial caster.
2. TPR: Technically, TPR is TPE because both of them belong to Polystyrene elastomer category. Its characteristics are similar to TPE, However, its elasticity is better than TPE as it is mainly made from SBS and its wear resistance is not as good as TPE. More important, TPR has better price than TPE, it also can be coated and formed with hard plastic like PA,PP. It can be used for heavy duty caster.
3. TPU: With the best wear resistance, good oil resistance, good elasticity and good load capacity, it has the longer service life, but it’s a bit noisy when working and without resistance to hydrolysis. It can be used for luggage caster and various types of industrial caster.
How to choose the above three caster materials?
Actually We are not able state which material is the best one since different caster materials have different advantages. The key to choose ideally caster materials depends on the usage and positioning of products. We seldom use TPE for caster even its price is moderate, mostly we use TPR and TPU. If you want the best wear resistance, then TPU is your best choice; If you want better price, then TPR is the most appropriate choice.
