Industrial Antioxidants

MTBHQ can be used as an antioxidant for volatile liquid organics: along with halogenated hydrocarbons, oils and fats (waxes), ethers, aldehydes, or in products containing those components. Commonly introduced at zero.01%-1.zero%, its antioxidant impact is notably higher than that of hydroquinone.

MTBHQ is an effective garage stabilizer for unsaturated polyester resins and other polymerizable organics, as well as a stabilizer for highly reactive resins. 

A. It has a full variety of capabilities and may play a very good function in a huge temperature range, nonetheless has a good blocking impact at 114℃, and best barely prolongs the curing of resins at expanded temperatures. 

B. In the excessive-temperature curing kind pultrusion, molding kind resin can higher reflect the awesome impact of polymerization [while "tert-butyl catechol" by thermal decomposition, will lose the effect of polymerization, and even affect the color of the resin]. 

C. Properly solubility, no pollutants to polyester products, can react quick with loose radicals to obtain the impact of polymerization. Unsaturated polyester resin because the matrix of synthetic resin adhesives, because of its strong adhesion, speedy infiltration velocity, low viscosity, is extensively used as pressure-sensitive adhesive tape, if the formula added 0.5% of MTBHQ as a warmness stabilizer, it is able to be an awesome manner to prevent the adhesion of the adhesive because of getting old problems.

Product Details

White to light gray crystal or crystalline powder, with unique odor, melting point 126.5~128.5℃, boiling 300℃, slightly soluble in water (25℃, <1%), easily soluble in ethanol (120%), acetone (190%), ethyl acetate (100%), insoluble in toluene, and soluble in animal and vegetable oils. MTBHQ is specially used as polymer inhibitor, heat and mild stabilizer and industrial antioxidant. This product has higher solubility and higher resistance to excessive temperature, so it has a much wider range of utility than "hydroquinone".

Industrial Antioxidants



MTBHQ is an effective anti-fisheye agent: Within the technique of polymerization, if the polymerization reaction pace is simply too rapid, it will lead to some debris no longer plasticized, so that "lumps" and "brilliant crystal spots" are shaped in percent merchandise, usually referred to as "the reasonable use of MTBHQ will significantly reduce the variety of fisheyes in the goods.

MTBHQ can be used as an intermediate in prescribed drugs and other natural synthesis: MTBHQ has a hindered phenolic group.

MTBHQ may be used as a stabilizer for dyes and pesticides.

MTBHQ may be used as an antioxidant for business oils, fat, fatty acid esters, linseed oil, and so on.

MTBHQ may be used as an antioxidant for pigments, dyestuffs and pharmaceutical intermediates, and is likewise a new kind of inhibitor and antioxidant: while loose radicals are gift, it is able to upload to free radicals to eat them.

Caution:

Avoid using beneath sturdy alkali situations to avoid discoloration of the product. although MTBHQ is manufactured with the authentic crystals crushed right into a powder that could skip 60 mesh, it nonetheless needs to be combined thoroughly in the course of use to make sure uniform dispersion.

Package deal specification and garage: 25kg/drum; the product should be saved in a darkish, dry warehouse far from mild. Shield from moisture and heat, and do not store and shipping with corrosive and dangerous materials.
