How to identify the value of waste plastics, these four factors are crucial
1. Types of main materials
Commonly used are LDPE, HDPE, aBS, HIPS, Pa, PET, PC, etc. The market price of each type of plastic generally has a very big difference, and whether it is added, whether it is filled, whether it is fireproof, etc. The recycling price makes a big difference.
2, color
The color discrimination mainly includes two aspects: firstly, whether the material has not been processed yet, only one processing or multiple processing and recycling, whether the performance is good or bad, whether it is aging or weathering. Secondly, look at the color of the materials, the price difference of materials of different colors is very large.
3, form
The form of recycled plastic refers to the state in which the material is located, that is, the material is a rubber head, a nozzle, a support, an adhesive tape, a sheet, a wire, a reel or a drum.
4, the proportion
The ratio mainly refers to the proportion of each material in the recovered source. This is completely determined by experience. If it is not possible to estimate, it is best to test the object to ensure accuracy. This is recycling. The most critical point of plastics is that if the ratio is not accurate, it will cause a lot of damage.
