The main difference between the raw materials of PVC plastics and recycled materials is: the products produced from raw materials of PVC plastic granules are generally colorless and odorless, with good luster, good elasticity, very soft hand feeling, and the most important thing is hygiene and safety. ; The recycled material is melted and reprocessed, and the raw material is used for a period of time. During this process, the physical properties of PVC such as hardness and flexibility will be significantly reduced. The raw material of PVC plastic pellets has good mechanical properties such as tensile strength and good anti-aging properties; recycled materials are mainly recycled and reprocessed, and the cost is very low. The formulation of the raw material of PVC plastic pellets is controllable, and the content of heavy metals can be strictly controlled within the range specified by the industry; while the recycled material may have restricted substances (such as lead because the source of raw materials is uncertain) , cadmium) exceeding the standard. The raw material of PVC plastic granules is the primary color of PVC, which can be adjusted to the desired color with toner; while the recycled material is difficult to change in the color matching process due to the variety of raw material colors.
