Thermoplastic elastomer TPR (Thermo-Plastic Rubber), also called thermoplastic rubber, is transparent in appearance, solid-colored particles, and has rubber characteristics. TPR is a material that is thermoplastic and has the characteristics of chemical rubber. It has excellent resilience, soft touch, abrasion resistance and aging resistance. TPR is a blended modified elastomer alloy based on SBS and SEBS thermoplastic elastomers. Its physical properties and hardness can be achieved by adjusting the types and proportions of various components to adapt to various industrial fields with different application requirements.
