Butylated Hydroxytoluene CAS:128-37-0 Introduction

BHT(Butylated Hydroxy Toluene) is applicable to various lubricating oils, re-processed gasoline, paraffin and other mineral oils, as well as to polyethylene, polystyrene, polypropylene, ABS resin, polyester, cellulose resin and foamed plastic (particularly to white or light-colored product), food-grade plastics, natural rubber, synthetic rubber, animal and plant grease etc.

Butylated Hydroxytoluene CAS:128-37-0

Application: Antioxidant BHT is an excellent universal phenolic antioxidant. It is non-toxic, nonflammable, non-corrosive, and has good storage stability. It can inhibit or delay the oxidative degradation of plastics or rubber and prolong the service life. The appearance is white or light yellow crystalline powder, soluble in benzene, toluene, methanol, ethanol, acetone, carbon tetrachloride, acetic acid, grease, ethyl ester, gasoline and other solvents, insoluble in water and dilute caustic soda solution. It is an excellent antioxidant additive for various petroleum products, widely used in various lubricating oils, gasoline, paraffin and various raw materials to prevent the acid value or viscosity of lubricating oil and fuel oil from rising. As a food antioxidant and stabilizer in food-grade plastics and packaged foods, it can delay the rancidity of food. It can also be used in polyethylene (PE), polystyrene (PS), PP (polypropylene), polyvinyl chloride, ABS resin, polyester, cellulose resin and foam plastics (especially white or light colored products), food grade plastics, natural rubber, synthetic rubber (styrene butadiene, nitrile butadiene, polyurethane, cis-1,4-polybutadiene rubber, etc.), animal and vegetable oils, and food and cosmetics containing animal and vegetable oils. The reference dosage is generally 0.1% - 1.0%.
