ULTRA-FLOW™ 500

ULTRA-FLOW™ 500 by Performance additives is a zinc soaps of unsaturated, high molecular weight fatty acids. It is a very effective material for the physical peptization of NR. It can be applied in polymer pre-mastication as well as in the masterbatch phase of single stage mixing. The available double bonds in ULTRA-FLOW™ 500 stabilize free radical formation, thus improving reversion resistance and tear strength. If applied at the recommended dosage which is 2 to 5 phr then it does not bloom from vulcanisates due to its high solubility level. As a process additive for solution SBR, it reduces compound viscosity and increases flow as well as reversion resistance. Can be stored for at least 2 years under normal conditions.
