  3. Uses:It can be used as antideteriorant in solid propellant to improve the storage stability of product , and it can be used for those rubbers and latices of natural, styrene-butadiene, acrylonitrile-butadiene,cis-1,4-polybutadiene,butyl,butylhedroxyl,cis-1,4-polyisopreneetc,so that to possess them those properties such as good resistance to many times of flexure and chap-resisting , highten the elongating strength , strengthen the defending function to hot-oxygen , ozone and some harmful metals such as copper , manganese and so on , and do not influence vulcanization of those rubbers. It can be resolved manifold problems 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 referential dosage is 0.2-0.3%.
  
  4. Safety notes:The product is considered toxic. When handling it should be worn dust gauze mask, rubber gloves and rubberized fabric protection clothing.
  
  5. Package:Laminated film knitting bag, in which is put plastic bag, net weight 20 kg a bag.
  
  6. Storage:Keep in a shady and ventilating place. Its shelf life is 12 months. The product can be still used if up to standard through retest after the specified date.
  
  7. Transportation：Prevent high temperature, sun-scorched and rain drenched during transportation.
