TPR material is a thermoplastic soft rubber material that has rubber elasticity and does not require vulcanization, and can be directly processed and molded (such as injection molding, extrusion, blow molding, etc.). It is made by blending thermoplastic styrene butadiene rubber (such as SBS, SEBS) as the basic raw material, adding resins (such as PP, PS), fillers, plasticizers, and other functional additives for modification. TPR materials often have the resilience and good wear resistance, slip resistance, and shock absorption properties of general rubber, but their softness and comfort are superior to rubber. TPR material has the characteristics of environmental protection, non-toxic safety, wide hardness range, excellent coloring, soft touch, weather resistance, fatigue resistance, temperature resistance, and superior processing performance. It is widely used in industries such as medical, automotive, and electronic communication
