Definition and classification of recycled plastic pellet industry
In our lives, plastic waste is everywhere, and recycling it can be made into pellets for use in all aspects of life. Today, China Plastics Network - Jiuzhi Plastics Co., Ltd. tells the definition and classification of the recycled plastic pellet industry:
Recycled plastic pellet industry definition:
2016-2021 Recycled plastic pellets market competitiveness survey and investment prospects report shows that recycled plastic pellets belong to the category of plastic pellets, and recycled plastics are recycled new materials or discarded plastics through the mast machine. The plastic produced is then cut into pelletized plastic pellets by a pelletizer.
Recycled plastic pellet industry classification:
Recycled plastic granules are mainly classified according to the different raw materials used and the characteristics of the processed plastic granules, and are generally classified into one, two and three grades.
First grade material:
It means that the raw materials used are scraps that are not grounded, or called chamfers, some are spouts, rubber heads, etc. The quality is also good, that is, it has not been used, in the process of processing new materials, the rest Small corners, or raw materials that are of poor quality. The particles processed from the wool have good transparency and the quality can be compared with the new material, so it is a first-class material or a special material.
Secondary material:
It means that the raw materials have been used once, except for high-pressure granulation. In the high-pressure granulation, most of the imported large parts are used. If the imported large parts are industrial films, they are not exposed to the wind and the sun, so the quality is also very good, processing The transparency of the particles is good, and it should be judged according to the brightness of the particles and whether the surface is rough.
Three-level material:
It means that the raw materials have been used twice or more, and the processed particles are not very good in terms of elasticity and toughness.
Plastic premium:
Close to raw materials, 80-90% of raw material prices;
Level 1: 70-80% of the price of raw materials;
Level 2: 50-70% of the price of raw materials;
Level 3: 30-50% of the price of raw materials.
Sometimes from the quality points: drawing, blown film, spinning, primary, secondary, injection molding and so on. Sometimes it is reclassified at the same level.
