How is plastic material made out?
The main components of plastic resin (in the early stage of coal tar products and calcium carbide carbide, it is used for oil and natural gas products, such as ethylene, propylene, benzene, formaldehyde and urea).
At present, resins are polymers that have not yet been blended with additives. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics depend mainly on the nature of the resin, but additives also play an important role.
Some plastics are made up of synthetic resins, with or without additives such as plexiglass and polystyrene. The so-called plastic, in fact, it is a kind of synthetic resin, the shape of the natural resin with pine resin similar, but also because of the chemical strength of the synthesis, and is called plastic.
