EconCore chooses MEAF extruder

polymer & packaging news agency - www.ppna.ir

EconCore  has chosen the high-speed, energy-efficient MEAF 50-H34 extruder for its trial production of recycled PET ThermHex honeycomb sandwich panels . 

The rPET honeycomb core is made of 95 per cent recycled post-consumer PET from bottles, combining sustainability with superior mechanical properties. The new extrusion technology will also feature prominently on the MEAF stand at K 2019 (Hall 17, Booth A22).

Wouter Winant, Technical Manager at EconCore, said: “We want to bring a smart, innovative and sustainable product to market that contributes towards the circular economy of plastics. Our rPET core offers high stiffness and strength in compression and shear, high temperature stability and excellent weight-to-cost ratio. In addition to the CO2 reduction …  the rPET honeycomb core further reduces the CO2 footprint thanks to the lower weight of manufactured parts. Of course, this needs to be produced in a cost-effective way, for which we have chosen the MEAF  50-H34 extruder, as an economical but highly efficient flat die extruder.”

Multiple applications

Ardjan Houtekamer, Technical Director at MEAF, added: “With their high throughputs, extruding up to 1,200kg per hour while using only 0.20kWh per kg, the sheet extruders of this series are currently among the most efficient in the market. Our extrusion lines are ideally suited for both single and multi-layer extrusion applications and can produce up to eight layers, using a range of materials including PP, PS, HIPS, PET, PE, PA, PLA, TPE, EVOH barrier and others.”

The MEAF H-series extruders have a special energy-efficient design in which all important parts have been optimised by the company’s engineers.

EconCore’s thermoplastic honeycomb technology allows for production of honeycomb panels within a continuous and in-line integrated process. Polymers are extruded, vacuum formed and folded into a honeycomb core. This results in a highly cost-effective process, ideally suited for large volume applications. Furthermore, lamination of skin layers is typically in-line integrated with the continuous honeycomb core production, allowing for one-shot production of added value sandwich panels or parts.

EconCore expects that the developed process and lightweight rPET products will mainly be offered to the automotive industry.
