1. Polyurethane foam (main)
Prevent the formation of peroxides during the storage of polyols
Avoid scorching / yellowing during foaming
Antioxidant 1135 improves the air-cooling process, prevents fogging of car interiors and fabric staining
2. Plastics and elastomers
PP, PE, PVC, SBS, TPE, etc., resistant to heat and oxygen aging, prevent yellowing, and do not flake
3. Lubricating oil / hydraulic oil
High-temperature antioxidant, extends oil life, and inhibits the formation of sludge
4. Adhesives / coatings
Antioxidant 1135 prevents oxidation and yellowing, and improves weather resistance
