Optimal large-scale polymer production industry usually consists of six processes: raw material preparation and refining, initiator (or catalyst) preparation, polymerization, separation, post-treatment and recovery. The importance of the auxiliary process will vary with different polymer varieties and production process conditions, but the polymerization process is always the core of the whole process. The polymerization reactor is the core of the core.
According to statistics in polymer production about 70% of the use of stirred tank, which is the most widely used polymerization reactor.
The tower type and special type polymerization reactors are mainly used for high viscosity polymerization in the combined system.

The goal of polymerization is to produce high molecular weight materials with specific structures. However, these polymerization processes are usually exothermic reactions, and the viscosity of the final product is usually very high. While processing extremely high viscosity materials, SUNKAIER kneader inputs or removes a lot of heat for the system to maintain the appropriate reaction material temperature for the bulk polymerization of drying and processing high viscosity materials.
Excellent mixing and kneading of paste and high viscosity phase (> 1000Pa · s);
Large capacity reactor can effectively handle mass production;
Larger heat exchange surface area maximizes productivity;
Shorten residence time allocation;
Highly flexible production capacity;
Closed environmental protection design;
Strong design, suitable for handling high viscosity materials;
The compact design maximizes the space-time output.
It is very important to accurately control the temperature of the product in the synthesis process. High surface renewal and evaporative cooling in the kneading reactor maintain good temperature control. Process parameters and product performance were systematically investigated in pilot production units. Then the industrial production system can be customized to meet the exact product requirements.
