The quality of recycled plastic is very critical. If the recycling quality is not well controlled, it will affect the performance and quality of the product. Recycled materials may introduce new pollution factors due to a cycle outside the production site, resulting in the generation of new defective products. So how to identify TPU recycled material?

1. Look at the brightness of the surface;

2. Look at the hardness, bite it with your teeth and you will know that the good materials are hard, and too soft means impure.

3. Look at the whiteness, not only on the surface, but also on the whiteness of the cut surface.

4. To see whether it is submerged, it depends on the amount of stone powder. Generally, there will be more or less stone powder in the recycled materials, because the incoming raw materials are not very pure. If no additional stone powder is added, generally it will not sink.

Recycled materials are generally produced by the recycling and reuse of chemical products. Through certain processing methods, various corresponding products are produced. The product requirements are different, and the properties of recycled materials are also different. In this way, recycled materials can be used to manufacture different products.
