What are the raw materials of plastics made of?

Answer:

The plastic is made of natural or synthetic resin as the main ingredient, adding various additives, in certain conditions such as temperature and pressure can be made into a certain shape, keep shape materials at room temperature.
Synthetic resin refers to coal, petroleum, natural gas, calcium carbide and some agricultural products as the main raw material, the low molecular weight compounds prepared firstly has certain synthetic conditions (monomer), and then through chemical and physical methods for the synthesis of high molecular compound. The characteristics of this kind of compounds similar to natural resin (such as rosin, shellac, amber, etc.), but the performance and more superior than the natural resin.
Some plastics are pure resins, such as polyethylene, polystyrene and so on. They are called single component plastics. Some plastics, in addition to synthetic resins, also contain other auxiliary materials, such as plasticizers, stabilizers, colorants, various fillers, etc., known as "multi component plastic.".
