Plastic is a polymer material. The molecular weight of the new material is reduced by 30% in theory after once used, 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 still incomparable with new materials. How do I distinguish between what is made with new materials and those made with recycled materials, the method:
1. Look at the gloss of the appearance, the surface, the gloss is good, the beautiful surface is made of new materials, and vice versa.
2. Measure performance indicators, which are similar to those in the physical properties table for new materials, and vice versa for recycled materials.
In the case of particles, recycled plastics have poor gloss, the surface of the particles is dull, the size is uneven, and they contain impurities, and they are generally colored or gray; the new material has good gloss, the surface of the particles is smooth, the size is uniform, no magazines, and most of them are colorless Or milky white. The new material is bright in color and the old material is dim in color.
