High moisture- and chemical resistance
High color fastness
High sound absorption
Easy cleaning
Easily recyclable (nontoxic, free of heavy metal)
Main applications
Multiple use as transport and storage boxes
Various thermal isolation applications
Automotive industry
Furniture and toys industry
Exercise balls and rollers
Load carriers
White goods protective packaging
Thermo boxes
Our unique foam extrusion team presents its newest development: Extrusion based expanded polypropylene. The extrusion process enables industrial molders to launch their own ePP production by developing their proprietary formulations with Borealis PP resin as raw material.
Borealis has developed a particular high melt strength PP grade particularly for the foam extrusion process, ePP beads produced with this resin can be molded using low steam pressure and standard molding Equipment.
New reliable foam extrusion process for production of ePP beads
The combination of a high-resolution loss in weight feeding system, a tailor-made twin screw extruder and an accurate direct injection of blowing agents such as carbon dioxide or isobutane into the PP melt ensures product specific characteristics and flexibility for a huge field of applications for the ePP industry.
Our unique melt cooling technology and an individual designed underwater pelletizing system completes the extrusion foam process for customized beads production.
