In order to improve the antioxidant capacity of foam products, we add antioxidants to the polyether production and foaming process (the combustion temperature of foam products can be increased to more than 180℃, and the amount added is related to the amount of water added).Increasing the combustion temperature of foam products avoids the occurrence of heartburn.
The color value is the most intuitive apparent index of polyether, and the quality of the color value can directly reflect the quality of the polyether.The carbon atoms on the polyetherether bond are easily oxidized, especially in alkaline media and at higher temperatures, which will cause an increase in side reactions and generate unsaturated bonds. If the color value is dark, other corresponding indicators (such as AV, unsaturation, etc.) will also change accordingly, and the color of foam products will change accordingly.
