Method for improving weather resistance of PVC foam boardMethod for improving weather resistance of PVC foam board
Over time, PVC foamed panels will fade and age due to changes in sunlight and temperature. Let us introduce some methods to improve the weather resistance of PVC foam board.
Titanium dioxide improves weather resistance. The addition of rutile titanium dioxide to PVC products can effectively improve the heat resistance, light resistance and weather resistance of PVC foamed sheets, improve the physical and chemical properties of PVC products, and extend the service life. In order to meet the requirements of long-term outdoor use, PVC sheets must have good weather resistance. However, the effective method for white PVC materials to resist ultraviolet damage is to add high weather resistance rutile titanium dioxide.
PVC foam board manufacturers use nano-cerium oxide to improve weather resistance. In order to improve the weather resistance of PVC building materials, they added vinyl chloride resin, ultraviolet absorbers such as ketone and benzene light benzene. Add nano cerium oxide to the mixture of vinyl resin, stabilizer, slip agent, processing aid, modifier, filler, plasticizer, antioxidant and ultraviolet absorber, or used to replace ultraviolet absorption Agent, can significantly improve the weather resistance of PVC building materials, and maintain good mechanical strength and transparency for a long time. The weather resistance of the PVC foam board is improved, the service life of the PVC product is greatly extended, the quality of the PVC product is more stable, and resources are saved.
