Santoflex™ 7PPD

Technical Datasheet | Supplied by Eastman
HSP Distance with Rubber Accelerator DPG(D) (First-class): 3.4
Santoflex™ 7PPD by Eastman is an effective polymerization inhibitor, antioxidant and antiozonant. It provides protection against fatigue degradation in both static and dynamic operating conditions. It imparts excellent high-temperature fatigue, flex resistance and ozone protection. It is less affected by environmental variables such as heat or leaching leading to greater durability, due to its specific molecular structure and higher rubber solubility. It possesses rubber protection against catalytic degradation by copper and other heavy metals. It is compatible with natural and synthetic elastomer compounds and offers stability with a wide range of solutions and emulsion polymers. It is used as an inhibitor in styrene monomer, p-methylstyrene, divinylbenzene and acrylate esters production and as a column antifoulant. Santoflex™ 7PPD is designed for polymer modification, pneumatic tire components, solid tires, belts, hoses, cables, automotive mounts, bushings and general mechanical products. It has a shelf life of 24 months.
