CAS 74-31-7 HS : 2921590090 25kg/drum, 200kg plastic drum, 200kg steel drum; 1000kg IBC, or as per your requirement. It can be used as the antioxidant to prolong the storage shelf life of the solid propellant. It has also been used for those natural, styrene-butadiene, acrylonitrile-butadiene, cis-butadiene, butyl, hydroxyl termindated polybutadienen, polyisoprene rubber or latex to possess performances, such as, good flexible and crack resistance, enhancing the tensile stress, strengthening the defending function to hot and oxygen, ozone and some harmful metals like copper, manganese. It has no influence on vulcanization of those rubbers. It can resolve aging problem existing in the deep-color rubber products while antioxidant H is used together with antioxidant D. Moreover, it can also be used as the hot and oxygen stabilizer for those engineering plastics, such as polyethylene, polypropylene, polyamide, polyformaldehyde and etc to improve their climate-resisting performance. The suggested dosage is 0.2-0.3%.
