ULTRA-FLOW™ 500 is a very effective additive 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. ULTRA-FLOW™ 500, if applied at the recommended dosage, does not bloom from vulcanisates due to its wide solubility limit. As a process additive for solution SBR, ULTRA-FLOW™ 500 reduces compound viscosity and increases flow as well as reversion resistance.
