TPR caster and TPR caster performance characteristics
TPR is a thermoplastic elastomer (TPE), also known as thermoplastic rubber (TPR). It is a kind of material with both rubber and thermoplastic properties. It can process rubber products as quickly, effectively and economically as thermoplastic plastics. Therefore, thermoplastic elastomer is a kind of plastic in terms of processing, and a kind of rubber in terms of its properties. Thermoplastic elastomer has many advantages over thermosetting rubber. At present, there is no uniform nomenclature for thermoplastic elastomer, and it is customary to use English abbreviation TPR to denote thermoplastic rubber. Some factories also call it artificial rubber castors.
1. Superior physical properties: good appearance and texture, mild touch, easy coloring, uniform and stable tone;
2. Excellent chemical properties: resistant to general chemicals (water, acid, alkali, alcohol solvent), can be soaked in solvent or oil for a short time;
3. The hardness ranges from 60A to 90a;
4. Quiet operation, no noise interference, can achieve mute effect;
5. Excellent UV and ozone resistance;
6. Excellent damping effect and good anti shrinkage property;
7. The tensile strength can reach more than ten MPa and the elongation at break can reach more than ten times;
8. In the floor does not leave traces, unlike rubber wheel will have sulfur and carbon black precipitation;
9. Weather resistance and no corrosion, can be applied to all kinds of harsh and extreme environment at home and abroad;
10. Good temperature resistance between - 50 ℃ and 115 ℃;
11. High load (100-500kg), high wear resistance, high springback, more than 70% backwash elasticity;
12. It has excellent adhesion with other plastics and can be directly mixed with PP, ABS and other plastics to make special plastic alloy;
13. Excellent safety and health performance, the product also has non-toxic, pollution-free and recyclable secondary processing environmental advantages.
TPR caster is widely used in medical industry, electronic industry, electrical equipment industry, supermarket shopping cart, high-grade trolley.
