The appearance is a light yellow tablet or a milky white powder with good fluidity; The molecular weight ranges from 600 to 700, with an average molecular weight of 650; The bulk density ranges from 300Kg/m3 to 350Kg/m3, with a specific gravity of 1.10 and a flash point of 416 ℃; The average particle size is 10 μ M. This product is soluble in aromatic compounds, ketones, and alcohols, but not in water and aliphatic compounds.

Characteristics and advantages: It is a highly active, low volatile, versatile, and pollution-free polymerized hindered phenolic antioxidant. It is a recommended excellent antioxidant for natural and synthetic rubber polymers and butadiene compounds, and also has excellent antioxidant effects in latex, with excellent dispersibility or compatibility. Under repeated washing and steaming of rubber, elastic silk thread, carpet primer, foam and other materials, it shows low mobility or withdrawal.

Usage 1. Mainly used to protect light colored, stain free compounds, such as natural rubber, sealant, ABS, BR, IR, NBR, NR, SBR, SBS, SIS and other derivatives.

2. It can be used in the processing of polymers, such as elastic silk thread, carpet backing, foam rubber pad materials, shoe sole materials, household and surgical rubber gloves, medical products, baby pacifiers, rubber additives, thermos bottles, bathroom mats, auto parts, paper coating, etc., to enhance stability.

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

4. It can be used as an efficient polyphenol additive.

Toxicity: This product has low toxicity
