Roben Mfg, Inc. fabricates dual-zone reactors with separate heating chambers for polymerization processes.
Our specialized reactor designs enable controlled polymer synthesis with independent temperature management
for initiation, propagation, and finishing stages, supporting production of polymers with specified
molecular weight and properties.
Dual-Zone Reactors for Polymerization Processes
Polymerization processes require careful temperature control to manage reaction kinetics, molecular weight
development, and heat removal during exothermic reactions. Our dual-zone reactors with separate heating
chambers provide independent thermal control for different polymerization stages, enabling optimization
of initiation temperature, reaction temperature, and post-polymerization processing.

Frequently Asked Questions
How do dual-zone reactors benefit polymerization processes?
Dual-zone reactors allow different temperatures for initiation and propagation stages, or for
polymerization and devolatilization. This enables optimization of reaction kinetics while managing
heat removal and controlling final polymer properties such as molecular weight distribution.
How do your reactors handle polymerization exotherms?
Our dual-zone reactors feature enhanced heat transfer through optimized jacket design, internal cooling
coils, and effective mixing. Heat removal capacity is engineered for your specific polymerization
exotherm, with safety systems for temperature excursion prevention.
Can your reactors handle the viscosity increase during polymerization?
Yes, our polymerization reactors feature high-torque agitation systems with polymer-appropriate impeller
designs. Agitation maintains mixing effectiveness and heat transfer as viscosity increases, with variable
speed drives adapting to changing process conditions.
