Generally speaking, plastic particles refer to granular plastics, which are divided into more than 200 types and can be subdivided into thousands of types.
Common plastic particles include general plastics, engineering plastics, and special plastics.
General plastics mainly include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, etc.
Engineering plastics mainly include nylon, polytetrafluoroethylene, polyformaldehyde, polycarbonate silicone, etc.
Special plastics mainly include thermosetting plastics and functional polymer plastics.

Substance types and applications of general plastics
Polypropylene (PP) is translucent, waxy, lighter than polyethylene, has better transparency than polyethylene, and is stiffer than polyethylene. Mainly used in pots, barrels, furniture, films, woven bags, packing tapes, bottle caps, car bumpers, etc.
Polyethylene (PE), milky white, translucent, waxy. It feels smooth to the touch, flexible and tough, and can be slightly stretched. Generally, low-density polyethylene is softer and has better transparency, while high-density polyethylene is harder. It 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 mostly used to make lampshades, toothbrush handles, toys, and electrical components. It is resistant to acid and alkali corrosion, but is easily soluble in organic solvents such as chloroform, dichloroethylene, 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.
