The main component of plastics is synthetic resin. The term resin is originally named after the lipids secreted by plants and animals, such as rosin, shellac, etc. Currently, the resin refers to a polymer that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with or without additives, such as plexiglass, polystyrene, and the like. The so-called plastic, in fact, is one of the synthetic resins, the shape is similar to the pine resin in the natural resin, but it is called plastic because it is artificially synthesized by chemical means.
