Application Instructions

A phenolic and environmentally friendly trialkane phosphite ester antioxidant. It is applicable to a variety of polymers, including polyurethane coatings, polyolefins, ABS, PVC, PET and lubricating oils, etc. It can provide good color improvement and thermal stability in both processing and later applications. As an efficient auxiliary stabilizer and chelating agent, it can be used in both rigid and flexible PVC materials, providing them with brighter and more uniform colors, and enhancing the transparency and thermal stability of the products. When applied in polyurethane foam, it can provide oxidation protection and reduce the risk of foam core burning and combustion, and has good anti-phenolic yellowing and anti-nox yellowing effects. Suggested addition amount: 0.1-2.0%
