After the plastics are recycled, the performance is reduced to varying degrees, mainly caused by photoaging, oxidation and heat aging. The extent of performance degradation depends primarily on age and environment.
The waste edge and waste products generated during the production of the molding processing plant have a small decrease in the performance of the recycled material, and can be used as a new material;
For indoor use and short-term products, the performance of recycled materials does not change much;
In outdoor use, products with long years and poor environment (such as pressure, electric field, chemical medium, etc.) have poor performance and cannot even be recycled.
Due to the heat aging during the regeneration process, the color of the recycled material changes from shallow to deep.
