Casters and wheels- the different between the TPR casters and TPU casters

The main differences between TPR and TPU caster materials are their physical and chemical properties, applicable scenarios, and price differences. ‌

TPR (thermoplastic rubber material) and TPU (thermoplastic polyurethane) caster materials each have their own unique properties and application scenarios. TPR caster material has the elasticity of rubber and the characteristics of plastic, and can provide good impact resistance, quiet effect and no damage to the floor. In addition, TPR material also has good weather resistance, low temperature performance, chemical resistance, waterproof and puncture resistance. TPR casters are suitable for occasions that require quiet effects, such as indoor tool carts, etc., and are available in a variety of sizes and styles. ‌

TPU caster material is known for its excellent wear resistance, oil resistance and good load-bearing capacity. Although it is noisy, it has a long service life. TPU material is not resistant to hydrolysis and is suitable for various industrial casters and luggage wheels. In terms of price, TPR caster material is usually cheaper than TPU, so it is more suitable in price-sensitive applications. ‌

When choosing TPR or TPU caster material, it is necessary to decide based on the specific usage scenario and needs. If you need a silent effect and the characteristics of not damaging the floor, TPR may be a better choice; if you require high wear resistance and long life, TPU is more suitable.
