Features and use of plastics: PE, PP, PVC, PC, PET
Plastic is a general term used for amorphous solid synthesized organic materials suitable for the processing of certain industrial products. Plastics are typically polymers of high molecular mass, which may contain some other elements to improve properties or used to reduce costs . To be able to distinguish between different types of plastic, one has to classify them. Plastics are generally classified based on chemical structure. In addition, they can also be classified based on the chemical method of synthesis.
