MAJOR APPLICATIONS AND PROPERTIES
it is a 1:2 blend of N-1,3-dimethylbutyl-N'-phenyl-p-phenylenediamine (6PPD) and N-1,4-dimethylpentyl-N'-phenyl-p-phenylenediamine (7PPD). Both constituents show comparable activity. Therefore, their blends can be regarded as similar to 6PPD in terms of performance in rubber.
it is provides efficient stabilization for a wide range of solution and emulsion polymerized elastomers that can tolerate discoloration.
The product provides powerful antiozonant and antioxidant properties with excellent high temperature flex fatigue resistance to rubber compounds.
it is a liquid at room temperature, providing handling advantages over heated liquid PPD's.
it is provides compound protection against catalytic degradation by copper and other heavy metals.
it 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.
