It is a colorless to light-yellow transparent liquid. It is essentially insoluble in water, soluble in most organic solvents, and classified as non-toxic.
It is a flowable liquid antioxidant characterized by low volatility and good compatibility. It is particularly suitable for air-cooled polyurethane processing and is effective in preventing fogging in automotive components as well as discoloration in textiles such as furniture fabrics, blankets, and hats. Due to its liquid fluidity, YFK-1135 is well-suited for processing polymers prepared in liquid, emulsion, suspension, solution, or molten states. It can be incorporated either before or after polymerization.
It is a highly effective antioxidant applicable to a wide range of polymers. It prevents superoxide-induced foaming in polyhydroxy compounds, thereby enhancing the storage and transportation stability of polyurethane foam boards. In addition, it regulates the foaming rate during polyurethane processing to prevent excessive or premature foaming.
This product is chemically stable and should be stored in a cool, dry, and moisture-proof environment.
The typical dosage range is 0.1% to 0.5％.
The product is packaged in 180kg steel barrel.
