- Mar 08, 2018 -

Generally refers to the production of large, widely used, molding good, cheap plastic. There are five major varieties of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene polymer (ABS). These five types of plastic occupy the vast majority of the use of plastic materials, the rest of the basic can be classified into special plastic varieties, such as: PPS, PPO, PA, PC, Pom, and so on, they in daily life products, the use of small, mainly in the engineering industry, National defense technology and other high-end areas, such as automotive, aerospace, construction, communications and other fields. Plastics are classified according to their plasticity and can be classified into thermoplastic and thermosetting plastics. Under normal circumstances, thermoplastic products can be recycled, and thermosetting plastic can not, according to the optical properties of plastics, can be divided into transparent, translucent and opaque raw materials, such as PS, PMMA, as, PC, etc. belong to transparent plastic, and most other plastic is opaque plastic.
