    Introduction of Inhibitor / Antioxidant TBHQ/ MTBHQ

     

    TBHQ is an oil-soluble antioxidant that prevents or delays the oxidative deterioration of fats in foods. As a food additive, TBHQ has been used in more than 20 countries such as the United States. In 1992, China was approved for use in oils and fats, dried fish products, biscuits, instant noodles, canned foods, and preserved meat products. The maximum allowable amount of TBHQ in food is 200 mg/kg. The United States stipulates that TBHQ alone or in combination with BHA and BHT should be used in an amount of 0.02% or less. Its antioxidant effect on oils and fats is better than BHA, BHT and PG with increasing concentration.

     

    Application

    MTBHQ is mainly used as a polymerization inhibitor for polymers, a photothermal stabilizer and an industrial antioxidant. This product has a higher solubility and better high temperature resistance, so it is more widely used than hydroquinone. Since MTBHQ has a hindered phenol group, it can also be used as an intermediate in pharmaceutical and other organic synthesis.

    MTBHQ can be used as an antioxidant for unstable liquid organic compounds, such as halogenated hydrocarbons, greases (waxes), ethers, aldehydes, or products containing these components. It is usually added in an amount of 0.01% to 1.0%, and its antioxidant effect is significantly higher than that of hydroquinone.

    MTBHQ is both an effective storage stabilizer for unsaturated polyester resins and other polymerizable organics, and a stabilizer for highly reactive resins. It is fully functional and can perform well over a wide temperature range. It still has good inhibition at 114 ° C and only slightly extends the curing of the resin at elevated temperatures. MTBHQ and oxygen form a polymerization inhibitor system and exert a good inhibition effect. Synthetic resin adhesive based on unsaturated polyester resin is widely used as pressure-sensitive adhesive tape because of its strong adhesion, fast infiltration speed and low viscosity. If 0.5% MTBHQ is added as light and heat in the formulation. Stabilizers can well prevent the problem of decreased adhesion caused by aging of the adhesive.

     

    In the polymerization process of vinyl chloride, if the polymerization rate is too fast, some particles will not be plasticized, so that special particals and "bright crystal dots" are formed in the polyvinyl chloride product, commonly known as "fisheye". MTBHQ is an effective anti-fish eye agent, and reasonable use will greatly reduce the number of fish eyes in the product.

     

    MTBHQ can also be used as an intermediate in pharmaceutical and other organic synthesis, as well as a stabilizer for dyes and insecticides. It can also be used as an antioxidant in industrial oils, greases, fatty acid esters, linseed oil, etc. It can also be used in pigments, dyes, pharmaceutical intermediates, antioxidants, and is also a new type of polymerization inhibitor, antioxidant, and free radicals. It can react with free radical addition to consume free radicals.

    Packing:

    25KG / barrel; this product should be stored in a dark, dry warehouse to protect from light. Prevent moisture and heat, and do not store together with corrosive and harmful substances.

     

    Note:

     

    Avoid using under strong alkali conditions to avoid discoloration of the product. Although MTBHQ has already pulverized the original crystal into a 60-mesh powder at the time of production, it still needs to be thoroughly mixed during use to ensure uniform dispersion.
