[0002] Plastic is a polymer compound made of monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role.
