 ANTIOXIDANT DTBHQ is generally used as a polymerization inhibitor, an antioxidant and a stabilizer. It is used mostly in industrial applications, particularly in rubbers, adhesive and adhesive films, paints, and monomers.

Stabilizer: It can strongly absorb ultraviolet wavelength of 280-310 nm. It is the thermal stabilizer for polyolefin fiber (dosage 0.5%) and film (dosage 0.01-2%) such as polyethylene, polypropylene, polyester resin (such as polyester). 

Inhibitor: it is the polymerization inhibitor for a variety of resin monomers. The effect is sustained and no color change when it is compared to hydroquinone. It has good inhibition to butadiene, vinyl acetate, styrene and other vinyl monomer.

Antioxidant: It can also be used as an additive for vegetable oils, increasing the oxidation resistance of oils and fats, stabilizing oils and extending storage period. info at www.zhiyi-chem.com
