Recently, Switzerland-based Sulzer Chemical Technologies and Austria’s Borealis jointly developed an innovative, cost-effective extrusion process for expanded polypropylene (ePP) beads. According to reports, this new PP foam extrusion technology can reduce the cost of the entire value chain and improve efficiency, support the end market's efforts to more circular solutions, and is expected to reduce manufacturing costs by 60%.
To support the large-scale adoption of ePP, Sulzer Chemical has now launched a new innovative compound production line. Unlike traditional autoclave production methods, Sulzer Chemical’s innovative system relies on direct gas-impregnated extrusion, providing an easy-to-implement alternative with a fast return on investment.
Foam molders, such as packaging manufacturers, can implement composite production lines to significantly reduce costs related to material supply, warehousing, and intermediate transportation. Therefore, the company can provide ePP parts at a more competitive price while supporting the use of polyolefin applications that are easy to recycle. Other benefits include complete control over the characteristics of ePP, such as bulk density, closed cell content, and bead size distribution, as well as maximum flexibility in fine-tuning the formulation. In addition, a highly automated process reduces maintenance requirements and simplifies operations. In addition, the extruded beads can then be easily processed in a steam chamber molding machine with standard steam pressure to obtain molded bead foam products with specific shapes.
In addition, Sulzer Chemical and Borealis are developing an alternative that can use carbon dioxide to support different customer needs and plant settings. "Working with industry leaders like Sulzer is a joy. This innovation will further promote the adoption of our PP foam solutions and support the transition of plastics to a circular economy. This is how we rebuild for a more sustainable life. Invented the way," said Christopher McArdle, vice president of Polyolefin Strategy and New Business Development for Borealis.
Torsten Wintergerste, President of Sulzer Division, said: "We are very satisfied with the advanced ePP production line jointly developed with Borealis. The results of this cooperation truly prove the extensive expertise of the two companies. Using our latest solutions, customers will Can benefit from cutting-edge equipment with enhanced performance and high-quality PP used to produce first-class foam."
This is a guideline for specifying screws and barrels that are continuously used under conditions that would crush standard equipment.
Maintenance departments often clean the screws incorrectly, causing serious and expensive damage.
TP polyester has more functions than you think. You may know PET, PBT and PETG-but what about PCT, PCTG, PCTA and PTT? If you are not sure what they are, how their properties compare and who sells them, we have the answer-and many new development reports.
