After the recycled plastics are recycled, the properties of the plastics are reduced to varying degrees, mainly caused by photoaging, oxidation and heat aging. The extent of plastic performance degradation depends primarily on the age of the plastic and the environment. The performance of recycled plastics is very small, and it can be used as a new plastic. For indoor use and short-life products, the performance of recycled plastics is not changed greatly. However, for plastics used outdoors, the performance of products with long years and poor environment is poor. It can't even be recycled.
After the plastics are regenerated, the performance is degraded, the color turns yellow, and the anti-aging property of the plastic drops the most. After the plastic is extruded multiple times, the viscosity of the high-density polyethylene decreases, and the viscosity of the low-density polyethylene increases. The amount of blending that can be added during recycling is generally 8% or less.
