Customized 2 shot plate injection molding Factory
Customized 2 shot plate injection molding Factory:Plastics can also be divided into general plastics and engineering Plastics. Its main purpose is to define a wide range of applications. Polyethylene and polypropylene, for example, are cheap and can be produced on a variety of different types of machines. Engineering Plastics are expensive, but the stability and physical properties of raw materials are much better.In general, they are both rigid and resilient.

Plastics can be divided into thermosetting plastics and thermoplastic two categories, thermosetting plastics can not be re-molded and used, and thermoplastic could be repeated production.
There are basically two types of plastic polymer structure: one is linear structure, the polymer compound with this structure is called linear polymer compound, the other is the ontology structure, the polymer combined with the ontology structure is called the bulk polymerization compound. Some polymers have branched chains, called branched-chain polymers, and belong to linear structures. Although some polymer molecules have cross-linked, but less crosslinking.
They are called mesh structures and belong to the structure of the human body. Two different structures exhibit two opposite properties. Polymers with linear structure (including branched chain structure) have the characteristics of elasticity, plasticity, solvent solubility, heating melting, low hardness, good brittleness and so on. Due to the lack of independent macromolecules, body structure polymers are not elastic and malleable, can not dissolve and melt, can only expand, with high hardness and brittleness. Plastics have two kinds of large molecular structures. Thermoplastics are made of linear polymers, and thermosetting plastics are made of massive polymers.
