After more than two years of hard work, our company’s technology research and development department has successfully developed China’s first TPE refrigerator door seal, which is a substitute for PVC refrigerator door seals. TPE refrigerator door seals are very strong in terms of performance and environmental protection. The advantage of is currently the most environmentally friendly material strongly promoted in Europe and the United States. It has excellent low temperature resistance, weather resistance, high elasticity, no migration, no halogen, high elongation at break and tensile strength that cannot be replaced by PVC refrigerator door seals. It is the preferred material for refrigerator door seals in the future.
