Elongational Rheology Extruder for Experimental Series



ERE Experimental Series is a new type of Elongational Rheology Extruder designed for research institutes, universities and enterprises to explore new formulations and processing technology of polymeric materials. 



Weak Shearing Force

Less damage of molecular chain basing on low shearing rate of material by ERE facilitates the extrusion of heat sensitive material with easy decomposition and narrow range of processing temperature.

Strong Elongational Force

High pressure of the material and strong elongational effect in the process of plasticizing is conducive to the blending and extrusion of different material systems with large fluidity difference.

Strong Conveying Capability

Based on the principle of complete pumping transportation with volume change and high extrusion pressure can be established by ERE which is suitable for processing ultra-high or ultra-low viscosity materials.

Homogeneous Compounding and Dispersion

The plasticization of materials dominated by elongation deformation in ERE can effectively break agglomeration of nanoparticles and realize the dispersion of nanoparticles in polymeric matrix.

Narrow Distribution of Residence Time

Linear positive displacement transport process of ERE avoids uncontrollable movement of material disorder and randomness in extrusion, and is suitable for processing of reactive extrusion.

Effective Compulsory Compatibility by PhysicalMeans

The compulsory dispersion and compounding of the elongation flow field makes the incompatible polymer show strong compatibility without adding compatibilizer.

Owing superiority of strong dispersion and compounding, less molecular weight degradation and low energy consumption by comparing with screw extrusion, ERE has wide applications in the processing of compatible extrusion with different polar materials, Nano-dispersion, thermal sensitive materials and other materials with extreme rheological properties. Simultaneously combining the functions of compounding performance from traditional "twin-screw" and direct forming from "single-screw, ERE provides a new experimental option for the optimization of polymeric processing technology.
