Therefore, to slow down the aging rate of PP corrugated sheets, the production formula can be appropriately adjusted according to different uses as follows:
1.Adding appropriate ultraviolet light absorber and antioxidant can effectively improve the sheets' weathering resistance.
2.To maintain the durability of the color, it is necessary to add weathering pigment to adjust the color of the swatch, such as iron oxide red, phthalocyanine blue, carbon black, green, and dioxin color, which can improve its weather resistance.
3.In the polypropylene hollow sheet formula, adding an appropriate amount of dioxins can greatly improve the weathering resistance.
4. In the polypropylene hollow sheet formula, a certain antimony stabilizer is added to replace the lead salt stabilizer, which has a corresponding improvement on the impact toughness and atmospheric aging resistance.
