PCR regenerated plastic particles were white non-toxic crystals. Good elasticity, high hardness and good tensile strength. It is a good raw material for making plastic products. It is mainly used in pots and pans, furniture, plastic bags, etc.
　　PCR recycled plastic particles belong to the category of plastic particles. Recycled plastics are the leftovers of recycled products. The used new materials or waste plastics are processed by physical or chemical methods such as pretreatment, melting granulation, modification and other physical or chemical methods to produce plastic particles, which are then cut into granules by a granulator. The method of re heating, plasticizing and pelleting is to reuse the plastics and solve the problem of pollution.
　　In our daily life, there are many plastic products. Let's introduce the types and uses of plastics. Plastic bags can be used to make plastic bags in our daily life. In the clothing industry, it can be used to make clothes, buttons, zippers, etc.; in terms of building materials, it can be used to make building tools, plastic doors and windows, etc.; in agriculture, it can be used to make agricultural film, agricultural machinery tools, fertilizer packaging bags, etc. In the mechanical industry, polypropylene particles are specially processed and can be used to manufacture mechanical parts, bearings, gears, sealing rings, pump impellers, etc. In a word, they are widely used in mechanical field. In the chemical industry, it can be used to manufacture pipes, containers, valves, etc., and can also be used in some chemical production sites with corrosion and wear. It will also be used in the automotive industry. In general, recycled particles will be used in all walks of life.
　　At the same time, PCR recycled plastic particles are mainly classified into grade I, II and III according to the different raw materials used and the characteristics of the processed plastic particles.
　　The first-class material refers to the leftover material without landing, or called bottom corner material, some of which are nozzle material and rubber head material, and the quality is relatively good, that is, the leftover small corner or raw material with poor quality during the processing of new material that has not been used. The particles processed with these raw materials have better transparency and their quality can be compared with new materials, so they are grade I materials or super grade materials.
　　Secondary material refers to the raw materials that have been used once, except for high-pressure granulation. Most imported large parts are used in high-pressure granulation. If the imported large parts are industrial films, they have not been exposed to the wind and sun. Therefore, the quality of the imported large parts is also very good, and the transparency of the processed particles is good. At this time, it should also be judged according to the brightness of the particles and whether the surface is rough.
　　The third grade material refers to the particles which have been used twice or several times, but the elasticity, toughness and other aspects are not very good.
　　Plastic super grade is close to raw materials, 80-90% of raw material price; first grade: 70-80% of raw material price; second grade: 50-70% of raw material price; third grade: 30-50% of raw material price. Sometimes from the quality points: drawing, blowing film, spray wire, first, second, injection filling, etc. Sometimes it's the same level.
