CumaPET L04 100

Design4Recycling: CumaPET L04 100 top layer
DuFor has developed CumaPET L04 100, which drastically improve recyclability and sealability compared to standard PET grades. When re-extruding APET sheet which is coextruded with a CumaPET L04 100 top layer, the end-product will be completely homogeneous with the same clarity as 100% virgin material. CumaPET L04 100 is characterized by lower melting and glass transition temperatures, which widen the processing window for sealing drastically. Further the packaging which is produced with CumaPET L04 100 is fully recyclable, and of course so is the trimming waste which originates during tray production. 

rPET main layer
When rPET is used for the main layer, the IV is often somewhat lower which results in a higher crystallization rate. If the tray will be recycled, with our L04 100 top layer, the crystallization rate, and thus the clarity of the main layer is improved.

There are also more possibilities to increase the recyclability of your packaging with our other CumaPET types. Interested in our CumaPET L04 100 or other specialty grades please contact us!

EconCore Teams up with Ultrapolymers and DuFor for Recycled PET Honeycomb Development

EconCore, the leader in thermoplastic honeycomb core production technology, collaborates with Ultrapolymers and DuFor in an R&D project funded by the Flemish Government to develop a new product: a thermoplastic honeycomb core made fromrecycled PET. The basis of this development is EconCore’s worldwide patented process for continuous and cost-effective production of thermoplastic honeycombs.

Ultrapolymers and DuFor, who have partnered with EconCore on this project, have extensive knowledge and expertise in processing PET and recycled PET (rPET) polymers. DuFor’s advise was of key importance to find the optimal composition of the PET polymers and chemical additives that benefit the crystallization process, even during fast cooling, and keep the semi-crystalline state stable during and after the manufacturing process.

The two-year project was funded by the Flemish government who acknowledged the innovative technology and ecological aspect in this new product and process development. Using the existing patented ThermHex technology which allows for fast, continuous production, EconCore managed to further improve and upgrade the process to allow the use of recycled materials that are being converted into high performing cost-efficient honeycomb cores.

 “We are delighted to work together with Ultrapolymers, one of Europe’s leading polymer distributors, and DuFor, a polymer developer and producer with over 40 years of experience. Thanks to their knowledge in polymers, EconCore managed to develop a sustainable honeycomb core which is made entirely from recycled PET materials.” said Wouter Winant, Technical Manager at EconCore. “These PET honeycomb cores and PET-based semi-finished sandwich panels can be used in a range of different applications, including transportation, building & construction, packaging, furniture and others, where sustainable, low-cost but performing solutions are desired. An interesting feature is that EconCore’s PET honeycomb materials are thermoformable and relatively complex shaped parts can be obtained. Furthermore, these honeycomb cores, although they remain very cost competitive, show enhanced stability at elevated temperatures. These products have a huge potential to become a more cost-effective alternative solution to solid polymer sheets and foam cores, particularly those based on PET.” continues Winant.

“By joining forces with EconCore, we are thrilled about the possibility to test and eventually bring to market a smart, innovative and sustainable product that contributes towards the circular economy of plastics” says Dieter Vogeleer, Account Manager at Ultrapolymers.

“Being involved in this project is in line with our focus to provide innovative and customized solutions for applications or products where recycled PET materials are used” said Marco Brons, Technical Director at DuFor.

About us

Company details

Together we can make the polyester with the best properties your product needs. We develop customized raw materials combined with a high level of technical support. Typical applications for our specialty polyesters are packaging both rigid and flexible, strapping, monofilaments, fibers and other high demanding technical applications. DuFor focuses on developing innovative polyesters that are recyclable and made with renewable resources. 

Customized Raw Materials
Using over 40 years of experience in polymer development and processing in a variety of markets and applications, we are able to translate our customers’ requirements into the recipe of the polymer needed. When the product requires special properties that are not available we develop it together with our customers. We do this by modifying the polymer structure through adding or changing comonomer content, additives, catalysts, changing the molecular weight (IV), compounding, blending or a combination of the before-mentioned. Our goal is to find the perfect polymer formula to meet your needs, from concept to product launch.
