The full name of TPR is Thermoplastic rubber. It is a kind of rubber with high elasticity, high strength, high resilience and can be processed by injection molding. It is environmentally friendly, non-toxic, safe, wide in hardness and excellent in coloring. With soft touch, weather resistance, fatigue resistance and temperature tolerance, TPE is easy to recycle and reuse for reducing costs. The waste generated during the production process (emission of burrs, extrusion of waste rubber) and the final defect or old products can be recycled after simple regeneration, reducing environmental pollution and expanding the source of renewable resources.
