Yiwu Sansheng Toys Co., Ltd .
1. more environmentally friendly: TPE, TPR relative to PVC does not contain phthalic acid ester plasticizer, no halogen, material combustion does not release dioxin and other harmful substances.
2. processing characteristics, flow characteristics, overall, TPE, TPR mobility is worse than PVC, TPE, TPR plasticizing and molding temperature is higher than PVC.
3.TPE, TPR can be used for injection molding, extrusion and blow molding. PVC can be molded by injection, extrusion, enamel (glue) and dropping glue (drop molding, micro injection).
4. hardness Description: PVC hardness unit is P (expressed as plasticizer content), TPE, TPR hardness unit is A (measured by data from shore hardness tester A). There is an approximate conversion relationship between P and A, the two hardness.
5. low temperature resistance: TPE, TPR compared with PVC, has better low-temperature resistance, that is, TPE, TPR at low temperature -40 -40 constant hardness, PVC at -10 temperature will be hard.
