　　Properties Appearance: light yellow tablets or milky white powder with good fluidity; molecular weight 600-700, average molecular weight 650; bulk density 300Kg/m3～350Kg/m3, specific gravity 1.10, flash point 416°C; average particles The size is 10 μm. This product is soluble in aromatic compounds, ketones and alcohols, but insoluble in water and aliphatic compounds.

　　Features and superiority is a high activity, low volatility, multi-purpose, pollution-free polymerized hindered phenol antioxidant. It is a recommended excellent antioxidant for natural and synthetic rubber polymers and butadiene compounds. It also has a good antioxidant effect in latex and has excellent dispersibility or compatibility. Under the repeated washing and cooking of rubber, elastic thread, carpet primer, foam and other materials, it shows low mobility or extraction.

　　Uses 1. Mainly used to protect light-colored, non-polluting color compounds, such as: natural rubber, sealants, ABS, BR, IR, NBR, NR, SBR, SBS, SIS and other derivatives.

　　2. Can be used in the processing of polymers, such as: elastic thread, carpet backing, foam rubber cushion material, sole material, household and surgical rubber gloves, medical products, baby pacifiers, rubber additives, thermos bottles, bathroom mats, Auto parts, paper coatings, etc., enhance stability.

　　3. This product can protect natural and synthetic polymers based on isoprene and butadiene chemistry.

　　4. Can be used as an efficient polyphenol additive.
