Santoflex™ 6PPD Liquid

Santoflex™ 6PPD Liquid by Eastman is N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine. Acts as an antioxidant and antiozonant. Provides protection against fatigue degradation in both static and dynamic operating conditions, catalytic degradation by copper and other heavy metals. It gives efficient stabilization for a wide range of solution and emulsion polymers. Due to its specific molecular structure and higher rubber solubility, it is less affected by environmental variables, such as heat or leaching, leading to greater durability. Compatible with natural and synthetic elastomer compounds. Santoflex™ 6PPD Liquid is suitable for use in pneumatic tire components, 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. Recommended dosage is 1-3 phr. It has a shelf life of 90 days.

Hansen Solubility Parameters

[18.8, 4.1, 6.3]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Santoflex™ 6PPD Liquid. A practical determination of these HSP values would provide higher certainty. Learn More.
