DURAZONE™ 37 is an easily dispersed, non-staining, and non-migrating antiozonant, ideal for rubber compounding.
DURAZONE™ 37 is a non-staining antiozonant that offers superior static and dynamic ozone protection and excellent antioxidant protection. DURAZONE™ 37 disperses easily and is ideal for use in rubber compounding. DURAZONE™ 37 antiozonant offers excellent protection protects without staining while improving flex life and static ozone protection. Incorporating DURAZONE™ 37 and a p-phenylenediamine offers the compound greater protection against ozone attack. The synergy between these two chemicals offers improves long-term static ozone protection. As a rubber compounding antidegradant, it is dosed at 2 to 4 parts per 100 parts RHC.
