Applications

YIPHOS® 1018 is a 100% phenol free and eco-friendly dialkyl Phosphite antioxidant, which can be widely used in polyolefins, lubricants, PVC and other polymers. YIPHOS®1018 can be used as an auxiliary stabilizer and mixed metal stabilizer for PVC materials, improving their initial color and anti-precipitation performance. When YIPHOS® 1018 is used for unsaturated polyester, it can suppress the yellowing caused by the resin synthesis process and maintain color stability. This product can also be used as an antioxidant and extreme pressure anti-wearing agent in lubricating oils.
