3. Uses: It can be used as the antioxidant in solid propellant to improve the storage stability of the product. It has been used for those natural, styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene rubber to possess performance such as good flex life and crazing for enhancing the tensile modulus, strengthening the defending function to hot-oxygen , ozone and some harmful metals such as copper, manganese with not 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 be also used as the hot-oxygen stabilizer for those engineering plastics such as polyethylene, polypropylene, polyamide, polyformaldehyde and etc to improve their climate-resisting performance. The reference dosage is 0.2-0.3%.
4. Safety instructions: Toxic. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing.
5. Package: Woven bag with inner plastic bag, 20 kg net each.
6. Storage: Store at cool, dry and ventilate. Shelf life of 12 months, if expire, still used if up to standard through retest.
7. Transportation: Avoid rain, moist, high temperature.
