Sulzer Chemtech Ltd. (Winterthur, Switzerland) and Borealis Group AG (Vienna, Austria) have completed the development of an innovative process for the cost-effective extrusion of expanded polypropylene (ePP) beads.
Polypropylene (PP) is a highly effective material, offering advanced mechanical properties and being well suited for reusing and recycling. To support the large-scale adoption of ePP, Sulzer Chemtech is now launching a new and innovative production line. Developed together with raw material supplier Borealis, the resulting solution supports the end market efforts towards more circular solutions and is expected to cut manufacturing costs by up to 60%.

Developed together with raw material supplier Borealis, the resulting solution supports the end market efforts towards more circular solutions and is expected to cut manufacturing costs by up to 60%.
As opposed to conventional autoclave production methods, Sulzer Chemtech’s innovative system relies on extrusion with direct gas impregnation, offering an easy to implement alternative with a quick return on investment. Foam molders, such as packaging manufacturers, can implement the compounding line to considerably reduce the costs associated with material supply, warehousing and intermediate transportation. As a result, companies can offer ePP parts at more competitive prices while su
