      Adopting special technology of synthesis and separation developed by the School of Chemistry and Chemical Technology of Shanghai Jiao Tong University.
      Easy using and high safety.
      Especially fit for poly(butadiene-styrene) and nature rubber.
      Chemical Name: 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline
      Molecular formula and Molecular Weight: C14H19NO=217.31  
      Molecular Structure:

      Application
      Main ingredient of Rubber Antioxidant AW is 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline or ethoxyquinoline. It is an excellent rubber antioxidant especially for nature rubber and poly (butadiene-styrene). It can improve rubber's anti-ozone, heat-resistant, antifriction and flexibility. Antioxidant efficacyis increased obviously when rubber antioxidant AW is used with antioxidant-H or antioxidant-4010 together.
