[0002] Plastic particles, also known as plastic granules or plastic raw material particles, are the basic raw materials in the plastic processing industry. They are usually the processed form of plastic resin and are used for further production processes such as molding, extrusion, and injection molding. Plastic particles can be classified according to different plastic types, molecular structures, additives, and colors.

[0003] Some common plastic particles include: 1. Polyethylene (PE): including high-density polyethylene (HDPE), low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE); 2. Polypropylene (PP): has good heat resistance and chemical stability, widely used in packaging, textile and automotive industries; 3. Polyvinyl chloride (PVC): divided into soft PVC and hard PVC, used for pipes, profiles, films and wires and cables; 4. Polystyrene (PS): including general polystyrene (GPPS) and high-impact polystyrene (HIPS), used for packaging materials, insulating materials and disposable tableware; 5. Polyethylene terephthalate (PET): mainly used for the production of fibers, films and bottles; 6. Polycarbonate (PC): has excellent transparency and impact strength, used to manufacture glasses, helmets and electronic product housings; 7. Nylon (PA): also known as polyamide, used to manufacture gears, bearings and fibers; 8. ABS resin: copolymerized by acrylonitrile, butadiene and styrene, used to manufacture electrical housings, toys and auto parts.
