Plastic is a monomer as raw material, through the polymerization or polycondensation reaction of polymer (macromolecules), commonly known as plastic (plastics) or resin (resin), can freely change the composition and shape of the form, from synthetic resins and fillers, plasticizers, stabilizers, lubricants,

Additives such as color materials. The main ingredient of plastic is resin. The term resin is originally derived from animal and plant lipids and the name, such as Rosin, shellac, etc., resin is not yet mixed with various additives polymer. The resin accounts for about 40%~100% of the total plastic weight. The basic properties of plastic mainly depend on the nature of the resin, but the additive also plays an important role.

Some plastics are basically composed of synthetic resins, without or less contain additives, such as plexiglass, polystyrene and so on. The so-called plastic, in fact, it is a synthetic resin, the shape and natural resin in the pine fat similar to the chemical method of artificial synthesis, and is called plastic.
