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.
