Customized 10L Jacketed Stainless Steel Reactor for PVAc Emulsion Production in Bangladesh

This week, we successfully delivered a customized 10L jacketed stainless steel reactor system to a client in Bangladesh for the production of polyvinyl acetate (PVAc) emulsion, commonly known as white glue.

PVAc emulsions are widely used in adhesives, coatings, and paint formulations, requiring precise temperature control and efficient mixing, especially when dealing with high-viscosity polymer systems.

Complete Reactor System Configuration

To meet the client’s process requirements for emulsion polymerization, the system was designed as a fully integrated solution, including:

• 10L jacketed stainless steel reactor (SUS316L/SUS304 optional)
• Circulating heater for precise temperature control
• Circulating chiller for rapid cooling performance
• Vacuum pump for degassing and process stability
• Peristaltic pump for controlled raw material feeding

This integrated setup ensures stable reaction conditions throughout the entire PVAc emulsion process.

Key Feature: High-Viscosity Agitator System

A major highlight of this project is the custom-designed agitator system, engineered specifically for PVAc emulsion rheology.

The mixing system includes:

• Frame-type anchor agitator
• Internal helical ribbon structure
• PTFE scraper blades for wall cleaning

This combination ensures:

• Uniform mixing of high-viscosity materials
• Effective prevention of material buildup on reactor walls
• Improved heat transfer efficiency
• Stable long-term operation during polymerization

High-Torque Drive System

To handle the increasing viscosity during polymerization, the reactor is equipped with an enhanced 750W drive motor, significantly more powerful than standard configurations.

This allows the system to:

• Maintain stable mixing from monomer phase to final emulsion
• Operate efficiently under high-viscosity conditions
• Ensure consistent product quality during scale-up trials

Application: PVAc Emulsion (White Glue) Production

The system is designed for:

• Laboratory and pilot-scale PVAc emulsion preparation
• Adhesive formulation development
• Process optimization and parameter testing
• Scale-up validation before industrial production

PVAc emulsion processes require strict control of temperature, agitation speed, and feeding rate, all of which are supported by this customized system.

Scale-Up Potential

The client will initially use this 10L reactor system for small-scale trials and process validation. Once the formulation is confirmed, the process will be scaled up to industrial production equipment.

This reflects a typical pathway from laboratory development to commercial manufacturing.

This project demonstrates our capability in delivering customized stainless steel reactor systems for polymer chemistry applications, especially for high-viscosity emulsion processes such as PVAc production.

By combining precise temperature control, high-torque mixing, and integrated auxiliary systems, we help customers achieve reliable and scalable process performance from R&D to production.
