APPLICATION
In the high-viscosity reaction system, twin-screw extruder has strong heat and mass transfer, nice interface renewal ability, narrow residence time distribution, excellent heat exchange and specific devolatilization surface, and easy continuous operation. 
 
Twin screw polymerization extruder (or twin screw reactor) not only has the physical processes of heat transfer, mixing, shearing, conveying, venting, and extrusion etc., but also polymerization and reaction. So the process is more complicated and the technology is more intensive. This kind of extruder is not frequently used, but important. Different syestem design and technical parameters are needed for different reaction types. Customized machine is needed for the specific raw materials to be processed and different polymerization process.
 
Typical processing includes continuous polymerization or reactive extrusion like dynamic vulcanization, crosslinking, grafting, and chain extension of PUR, PA, POM, PEI, PC, PMMA, PBT, PPS etc.
