Utilizing the continual periodic volume change of material during process, ERE conveys polymer by complete positive displacement with characteristics of high efficiency independency from material property and low energy consumption and so on.
Plasticizing and Mixing Process Dominated by Elongational Rheology
The plasticization and mixing process of ERE is dominated by elongational deformation, which shows advantages including high efficiency in matter and heat conveying, good dispersing ability, and low polymer degradation or fiber breakage caused by shearing.

Features
Short Thermo-mechanical Process
ERE has short thermo-mechanical process in material conveying and high efficiency in transferring mass and heat, which leads to obvious competitive edge in low energy consumption and less material degradation.
Low Energy Consumption during Plasticization Conveying
Proved by test and theory, specific energy consumption (SEC) for ERE is lower than conventional screw extruder and close to minimum SEC.

*Relation between Specific Energy Consumption and Polymer Throughput
Good Extrusion Stablility
In ERE, there is good linear relation between polymer throughput and rotate speed. The throughput does not change with die pressure, resulting in good stability for sheet, pipe and blow molding extrusion.
