Description and Uses
4,4'-Thiobis(6-tert-butyl-m-cresol) (Antioxidant 300), melting point 161-163℃, white powder, low volatility, low toxicity; soluble in organic solvents such as benzene, toluene, acetone, methanol, ethanol, carbon tetrachloride, slightly soluble in petroleum solvents, insoluble in water, is a non-polluting, high-efficiency phenolic antioxidant with low volatility, high antioxidant efficiency, good thermal stability and weather resistance, and little effect on the electrical properties of the product. It also has a synergistic effect when used with carbon black and octadecyl alcohol. It can be used as an antioxidant for polypropylene, ABS, polystyrene, polyphthalamide, polyurethane, etc., and is suitable for white, bright-colored and transparent products. It has very low toxicity and is allowed to be used in plastic products that come into contact with food in many countries.
4,4''-Thiobis(2-tert-butyl-5-methylphenol) is an antioxidant in the rubber and plastics industry. 4,4''-Thiobis(2-tert-butyl-5-methylphenol) is a radical inhibitor which prevents the thermal decomposition of the peracid. In addition, it is used as a stabilizer in polyethylene and polyolefin packaging materials for foodstuffs. Protection of light-colored rubber from oxidation and of nonstaining neoprene compounds against deterioration.
