Plastic particles refer to granular plastics, generally divided into more than 200 types and subdivided into thousands of types.
Common plastic particles include general plastics, engineering plastics, and special plastics.
General plastics : polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc.
Engineering plastics: nylon, polytetrafluoroethylene, polyformaldehyde, polycarbonate silicone, etc.
Special plastics : thermosetting plastics, functional polymer plastics, such as artificial kidneys.
Substance type
Introduction to PP recycled plastic : Polypropylene (PP) — translucent and waxy when uncolored, lighter than polyethylene, more transparent than polyethylene, and stiffer than polyethylene. Mainly used in pots, barrels, furniture, Film, woven bags, packing tapes, bottle caps, car bumpers, etc.
Introduction to PE recycled plastic: Polyethylene (PE) — milky white, translucent, waxy when not colored; feels smooth when touched by hand, flexible and tough, slightly stretchable, generally low-density polyethylene is softer and more transparent Better, high-density polyethylene is harder and is mainly used for mulch films, handbags, water pipes, and oil drums.
PS is polystyrene plastic, which is easy to color and has good transparency. It is often 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, dichlorethylene, banana water, etc.
PVC is polyvinyl chloride plastic, which is bright-colored, corrosion-resistant, strong and durable. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents during 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 colors, heat resistance, and strength. The outer surface can be plated with chrome, nickel and other metal films. It can be used to make piano keys, buttons, knife holders, TV casings, and umbrella handles. wait.
PA is nylon plastic. It is tough, strong and wear-resistant. It is often used to make combs, toothbrushes, clothes hooks, fan ribs, mesh bag ropes, fruit packaging bags, etc. It is non-toxic, but it should not be in contact with acids and alkalis for a long time.

Chemical industry : Regenerated particles can be used as reactors, pipes, containers, pumps, valves, etc., and are used in chemical production sites to solve corrosion and wear problems.
Classification
Recycled plastic particles are mainly divided into grades based on the different raw materials used and the characteristics of the processed plastic particles. They are generally divided into first, second and third grade materials.
First grade material
It means that the raw materials used are unfinished scraps, or scraps. Some are nozzle materials, rubber head materials, etc. The quality is relatively good, that is, they have not been used. In the process of processing new materials, the remaining Small corners, or raw materials of substandard quality. The particles processed from these wool materials have good transparency and their quality can be compared with new materials, so they are first-grade materials or special-grade materials.
Secondary material
It refers to the raw materials that have been used once, except for high-pressure granulation. Most of the imported large parts are used in high-pressure granulation. If the imported large parts are industrial films, they have not been exposed to wind and sun, so their quality is also very good. The particles that come out have good transparency. At this time, it should also be judged based on the brightness of the particles and whether the surface is rough.
Grade three material
It means that the raw materials have been used two or more times, and the processed particles are not very good in elasticity, toughness and other aspects.
Material application
Recycled plastic particles have a wide range of applications. In daily life, recycled particles can be used to make various plastic bags, barrels, basins, toys, furniture, stationery and other daily utensils and various plastic products. In the clothing industry, it can be used to make clothing, ties, buttons, and zippers. In terms of building materials, plastic wood profiles, derivatives of recycled plastic particles, are used to manufacture various building components, plastic doors and windows, etc. In the chemical industry, it can be used to make reactors, pipes, containers, pumps, valves, etc., and is used in chemical production sites to solve corrosion and wear problems. In agriculture, it can be used to make agricultural films, water pumping pipes, agricultural machinery, fertilizer packaging bags, and cement packaging bags. In addition, recycled particles are also widely used in the electrical industry and telecommunications industry.
