TPE,TPR (Thermoplastic Elastomer)
TPE/TPR (thermoplastic elastomer/thermoplastic rubber) is an innovative polymer material that combines the elasticity of traditional vulcanized rubber with the processability of thermoplastics. They eliminate the need for complex vulcanization processes and can be quickly formed through injection molding, extrusion, and other processes. They offer outstanding advantages such as environmental friendliness, non-toxicity, soft touch, strong weather resistance, and recyclability, making them an ideal alternative to PVC, silicone, and traditional rubber.
