ANTIOXIDANT HONOX-DTBHQis generally used as a polymerizationinhibitor, an antioxidant and a stabilizer. It is used mostly in industrial applications, particularly in rubbers, adhesive and adhesive films, paints, and monomers.

Stabilizer:Itcan strongly absorb ultraviolet wavelength of 280-310 nm. Itisthe thermal stabilizer forpolyolefin fiber (dosage 0.5%)andfilm (dosage 0.01-2%)such aspolyethylene, polypropylene, polyester resin (such as polyester).

Inhibitor:it isthepolymerization inhibitorfora variety of resin monomers. The effect is sustained and no color change when itis compared to hydroquinone. It has good inhibition tobutadiene, vinyl acetate, styrene and other vinyl monomer.

Antioxidant:Itcan also be used as an additive for vegetable oils, increasing theoxidation resistanceof oils and fats, stabilizing oils and extending storageperiod.

Rubberantiager:It is the excellent anti-aging agent forlight colored rubberproducts and the antioxidant fornatural rubber, synthetic rubber and latex, retarding the oxidation and UV aging ofthecured rubber and theuncured rubber.It alsohasthe performances ofheat resistanceand flex resistance. The synergism is realized when it is combined with anti-aging DNP.Itis also effective to theadhesive. It is easy to disperse in rubber products,non-discoloring andnon-staining.It can be used to the production of light color rubber products, medical products and latex products. The general dosage is 0.3-0.5%. info at hhochem. com
