🧪 Polymer Materials Field (Core Application)

This is the most important and classic application area for antioxidant 1135.

Polyurethane (PU) systems: This is its most prominent application. Adding antioxidant 1135 to polyurethane flexible foam production prevents the formation of peroxides in the raw material polyether polyol during storage and effectively avoids the “scorching” phenomenon caused by high-temperature oxidation during the foaming process. Its low volatility also helps reduce fogging on the surface of products such as automotive interiors.

Processing advantages: As a liquid antioxidant, it can be pumped, allowing for precise addition and mixing at any stage before, during, or after polymerization, especially suitable for emulsion polymerization and other processes. A typical recommended addition amount is 0.15% to 0.5%.

Synergistic use: To obtain more comprehensive stabilization effects, it is often used synergistically with other additives such as phosphites and light stabilizers (such as UV absorbers).
