Hard injection molded particles
Plastic particles refer to granular plastics, which are generally divided into more than 200 types, which are subdivided into thousands of types. Common plastic particles include general plastics, engineering plastics, and special plastics. General-purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbon silicone, etc. Special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys.
Introduction to PP recycled plastics: Polypropylene (PP) --- When uncolored, it is translucent, waxy, lighter than polyethylene, has better transparency than polyethylene, and is harder than polyethylene. Mainly used in basins, barrels, furniture, films, woven bags, packing belts, bottle caps, car bumpers, etc.
Introduction to PE recycled plastics: Polyethylene (PE) --- milky white translucent, waxy when uncolored; it feels slippery when touched by hand, flexible and tough, slightly stretchable, generally low-density polyethylene is softer and transparent Better, HDPE is harder. It is mainly used for mulching film, handbags, water pipes, oil drums.
PS is polystyrene plastic, which is easy to color and has good transparency. It is mostly used to make lampshades, toothbrush handles, toys, and electrical parts. It is resistant to acid and alkali corrosion, but is easily soluble in organic solvents such as chloroform, dichloroethylene and banana water.
PVC is a polyvinyl chloride plastic with bright color, corrosion resistance, strong durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process, its products generally do not store food and medicine.
ABS is a plastic polymerized by acrylonitrile, butadiene, and styrene. It has eye-catching color, heat-resistant, strong, and the outer surface can be plated with chrome, nickel and other metal films. It can be used to make keys, buttons, knife holders, TV casings, and umbrella handles. Wait.
PA is a nylon plastic. It is tough, firm, and wear-resistant. It is often used to make combs, toothbrushes, clothes hooks, fan bones, mesh bags, and fruit packaging bags. It is non-toxic, but it should not be in contact with acid and alkali for a long time.
