Reacting Twin Screw Extruder

TiERMAX’s reacting twin screw extruder is a unique new product developed by our partner’s experts in recent years and is available only through TiERMAX for the North American market. This generation of twin screw extruder is primarily utilized for the reactive extrusion of a variety of polymers. The designers and research team have done a lot of experiments on reacting extrusion over the last 20 years, so they know how to meet challenging processes.


The reacting twin screw extruder supplied by our company have been used for the production of a wide range of polycondensation, grafting, crosslinking products such as PVA (polyvinyl chloride), PA66 (polyethylene terephthalate), PCC (polycarbonate) , POM (polyoxometalate) and TPU (thermoplastic polyurethane), ABS, and other melamine materials. The technologies of PVA reaction extrusion and para-aramid reaction extrusion have addressed market gaps and advanced to an international advanced level.


TiERMAX can supply reacting twin screw extruder series in 10 different sizes. The screw diameter of this reacting twin screw extruder has a screw diameter range of 20 to 170 mm and the electric motor main power can be adjusted from 5 to 850 kW.

Application of Reacting Twin Screw Extruder:

Polymerization of POM, PVA, PP, Kevlar fiber, etc

Polycondensation of PA6, PA66, PBT, PET, PU, PPS, etc

TiERMAX’s Reacting Twin Screw Extruder:

The reacting twin screw extruder is a chemical reactor that carries out a variety of polymerization and polymer modification activities on a variety of different materials. Because of its unique design, this type of reacting twin screw extruder is capable of performing reactions on polymers with a high viscosity while also being extremely flexible (allowing the sequential addition of reaction ingredients such as reactant, monomer, solvent, polymer, and water) and simple to operate due to the independence of feeding rate and screw speed.

It has been specifically created to suit the requirements of cross-linking reactions, grafting reactions, polymerization reactions, polycondensation reactions, devolatilization reactions, and other related processes.

TiERMAX’s reacting twin screw extruders are available in a variety of screw element sizes, allowing us to satisfy a variety of customer requirements.

Designing for extremely long residence times, precise control of residence times, ultra-high temperatures, and self-cleaning properties all contribute to meeting the most rigorous and demanding industrial applications for chemical reacting processes available.
To be more specific, our reactive twin screw extruders have screw diameters ranging from 20mm to 170mm, depending on the model.
