Main identity and application;
With enhanced resistance to oxidation and ozone resistance, and thus give the rubber compounds excellent resistance to high temperature fatigue and flex resistance, is applicable to a wide range of solution-polymerized and polymer emulsion polymerization flexible
The antioxidant activity is higher than quinoline or diamine antioxidants, the longer lasting, better
Rubber has good resistance to poke and other heavy metals in catalytic degradation of performance, it is the amount of the two below, does not affect the adhesive properties of rubber and fabric or steel cord, the amount of more than two copies can cause blooming impact plasticlayer and the cord adhesion to rubber discoloration, causing severe contact and migration of pollution
