Types of blow molding materials
A. Polyolefins HDPE, LLDPE, LDPE, PP, EVA are generally used for blow molding industrial products, containers and toy accessories, storage containers for chemicals, etc.
B. Thermoplastic polyester
PETG and PETP are mainly used to blow carbonated beverage packaging bottles, wine bottles, etc., which have gradually replaced PVC and have been widely used. The disadvantage is that their cost is relatively high, and they are mainly used for injection stretch blow molding.
C. Engineering plastics (alloy)
ABS, SAN, PS, PA, POM, PMMA, PPO, etc. have been gradually applied in industries such as automobiles, medicines, home appliances, and chemicals, especially PC and its blended plastics, which can be used to blow high-end containers and automotive supplies (PC/ ABS, etc.).
D. Thermoplastic elastomer
SBS, SEBS, TPU, TPE, etc. are usually blow-molded as rubber materials, while thermosetting plastics, vulcanized rubber, and cross-linked PE cannot be blow-molded.
