Properties: A high activity antioxidant for natural and synthetic rubber provides powerful antiozonant and antioxidant properties with excellent high temperature, fatigue and flex resistance to rubber compounds. While used primarily for ozone resistance, it is a more active antioxidant than quinoline or diphenylamine-based antioxidants. The product (alone or in combination with TMQ) provides compound protection against catalytic degradation by copper and other heavy metals. The product has no negative effects on compound adhesion to textiles or steel cord up to levels of 2 phr. Above this concentration it may bloom and interfere with ply to ply and ply to cord adhesion. It will discolor compounds and cause severe contact and migration staining.

Application:  Used in all kinds of tyre and rubber products, solid tires, belts, hoses, cables, automotive mounts, bushings and general mechanical products that are exposed to continuous and intermittent dynamic operating conditions and require protection from ozonation.

Package: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag.

Storage: Store closed containers in a cool, dry, well-ventilated area, store far from strong oxidizing materials. Avoid exposure to direct sunlight. Do not double stack.
