The main component is a resin plastic. The term was originally a resin secreted by the animal and plant lipids named, such as rosin, shellac, resins and various additives that have not yet mixed polymers. 40% to 100% of the total weight of the resin approximately plastic. Basic performance mainly depends on the nature of the plastic resin, the additive also plays an important role. Some plastics are basically composed of a synthetic resin, without containing an additive or less, such as glass, polystyrene and the like. The so-called plastic, in fact, it is a synthetic resin, natural resin in shape with pine resin similar, but chemically synthetic means, which is called plastic.
Plastic is an important organic synthetic polymer material, is widely used. However, waste plastic to give the “white pollution” has become increasingly serious, if we can learn more about the composition and classification of plastics, not only can help us use science and plastics, but also conducive to the classification of plastic recycling, and effectively control and reduce “white pollution.”
