How to distinguish new raw materials and reworked plastic material

Plastic is a polymer material. The molecular weight of the new material is theoretically reduced by 30% after one use, which means that the various properties of the material are reduced by 30%. When the recycled material is recycled, some additives will be added, and various properties will be improved. , but it is still incomparable with the new material. How do you distinguish between those made with new materials and those made with recycled materials? Methods:

1. Look at the gloss of the appearance, the surface, the gloss is good, the surface is beautiful, it is made of new materials, and vice versa.

2. The performance indicators are measured, which are similar to the physical properties table indicators for new materials, and vice versa.

In the case of granules, the recycled plastic has poor gloss, the surface of the granules is dull, the size is uneven, contains impurities, and is generally colored or gray; the new material has a good gloss, the surface of the granules is smooth, the size is uniform, does not contain magazines, and most of them are colorless. or milky white. The new material is bright and the old material is dull.
