What is TPR?
“TPR” stands for Thermoplastic Rubber. TPR is a class of polymers that combines the characteristics of both thermoplastics and elastomers (rubbers). TPR materials are known for their flexibility, durability, and ease of processing. They are often used as a cost-effective alternative to traditional rubber materials in various applications.
