Technological Innovation

The technology theory of ERE takes advantage of the periodical volume change of material volume change of material during processing to realize polymer conveying. The technology shows outstanding characteristics including high efficiency, short process and low energy consumption, which provides a new and green processing technology for polymer industry.

Complete Positive Displacement Volume Conveying

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.

*The Influence of Die Pressure on Throughput

Less Molecular Weight Reduction

There is less molecular weight reduction for product by ERE, which facilitates the extrusion of heat seneitive material such as PVC, PVA and PET.

*Comparison of Molecular Weight before and after Extrusion

Homogeneous Mixing and Dispersion

During plasticizing process in ERE, polymer melting is dominated is dominated by elongational deformation in polymer matrix and facilitates general and engineering plastic modification.

*LDPE/Nano Calcium Carbonate

Self-reinforcement with Enhanced Orientation

After extruded with volume elongational deformation, crystalline polymers show strong orientation and high crystallinity. Elongational deformation facilitates crystal refine, which enhances the strength of PP, PA and PLA spinning.

Good Compatibility

With good compatibility for various polymer materials, ERE is able to complete mixing extrusion molding processing of high and ultra-low viscosity materials, such as m-PE, UHMWPE, high concentrated ,master batch and adhesive and so on.
