3. Usage                                                                                                                             

  • It’s 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.
