According to the molecular structure of synthetic resin, plastic raw materials mainly include thermoplastic and thermosetting plastics. For thermoplastic plastics, plastics that are plastically heated repeatedly: mainly PE/PP/PVC/PS/ABS/PMMA/POM/PC/PA And other common raw materials. Thermosetting plastics mainly refer to plastics made from heat-hardened synthetic resin, like some phenolic plastics and amino plastics, not commonly used.
According to the application range, there are general plastics such as PE/PP/PVC/PS, engineering plastics such as ABS/POM/PC/PA, etc. There are also some special plastics such as high temperature resistant, high humidity and resistant. Corrosion and other plastics modified for special purposes.
Nowadays, children’s toys are made of non-toxic plastics. The most commonly used PP is the world-recognized non-toxic plastic. The price of plastic products is not particularly demanding. (For example, the product is small and does not need to be strong. It does not need to be very hard. Allow the product to be deformed) will be used.
There is also ABS. We often see this plastic used on the battery car. The battery car is ABS except the black ones. The product he made is that the finish is good, the hardness is better than that of PP, the strength is good, the deformation is small, and the price is slightly higher than PP. It is a shell of a relatively large-scale toy car that is played by children.
