Naugard I-31 is a formulated blend of Naugard I-3 and Naugard I-5 which has been commercially proven to dramatically reduce polymer formation and tar viscosity in monomer manufacturing processes.
* Styrene monomer distillation
* Divinylbenzene distillation
* p-methylstyrene distillation
* Naugard I-31 has been used in one of the world largest styrene plants since 1984 and in other world-scale styrene plants since 1987 and 1990.
* Superior performance compared to dinitrophenol polymerization inhibitors, especially at elevated temperatures.
* Unique blend of both a true inhibitor (I-3) and a retarder (I-5).
* Less toxic than dinitrophenol alone.
* Supplied as a concentrated liquid in ethylbenzene or styrene to provide safe, economical, and facile handling.
* Higher solubility in ethylbenzene and styrene than dinitrophenol inhibitors
* Ratio of blend components formulated to meed individual customer needs and performance requirements.
* Maximum performance is attained in the presence of air. |
