2,5-Di-tert-butylhydroquinone CAS 88-58-4 DTBHQ

2, 5-di-tert-butylhydroquinone, DTBHQ, is widely used in the synthetic rubber, plastic, resin and other industries. It is applicable to ultraviolet absorbers for the modification of natural rubber, synthetic rubber, latex, polyolefin and polyoxymethylene plastics, resins and engineering plastics, etc. All kinds of rubber, developing materials, resins, plastics, oils and adhesives, etc. It is a non-toxic, odorless and pollution-free polymerization inhibitor for plastics and resins. DTBHQ is used as an inhibitor, especially in low-pressure environments. As an antioxidant, DTBHQ endows unsaturated polyester with good stability during production and storage. 2, 5-ditert-butylhydroquinone is used as an antioxidant for natural rubber, synthetic rubber and latex. It can delay the oxidation and ultraviolet aging of vulcanized and unvulcanized rubber, and is a non-polluting rubber product.
