Characteristics and uses This product is an excellent liquid hindered phenolic antioxidant with good antioxidant properties, with auxiliary antioxidants, synergistic stabilizers (such as: phosphite, phosphate, thioether, hydroxylamine, lactone ) And hindered amine light stabilizers (such as ultraviolet absorbers, hindered amines) have obvious synergistic effects when used in combination. It is especially suitable for polyurethane flexible foam rubber sheet, which can prevent the polyol from generating peroxide during storage, and can also prevent scorch during foaming. Due to its low volatility and excellent compatibility, it is particularly effective in the process of forced air cooling of polyurethane. This feature can also prevent fogging on the surface of products used in automobiles and coloring of textiles. Used in lubricating oil can significantly improve the high temperature stability of oil products.
This product has the convenience of pumping liquid additives, easy to use and effective mixing. In a single liquid, emulsion, suspension, solution or melt polymer manufacturing process, the low volatility and liquid state of antioxidant 1135 makes it particularly suitable for easy emulsification. It can be dissolved, dispersed or added during the process Keep pure liquid. It can be added before, during and after polymerization. The usual recommended dosage is between 0.15% and 0.5%.
Storage and packaging 180 kg/iron drum, stored in a dry and cool environment according to general chemicals, the recommended storage time is 12 months.
