SHANGHAI, China – November 1, 2022 – Avient today announced the addition of new high-impact polypropylene (PP) based grades to its Gravi-Tech™ density modified portfolio. Avient’s portfolio of Gravi-Tech materials combine the aesthetics of metals with the superior processability of polypropylene (PP), acrylic butadiene styrene (ABS), polyamide (PA), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), and other thermoplastic materials. Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint

THE CHALLENGE A leading North American manufacturer of polypropylene (PP) hose for medical applications, including laser surgery, respiratory care and sleep apnea equipment, faced a challenge with its existing thermoplastic vulcanizate (TPV). The Avient team assessed the application’s technical and operational requirements, and recommended GLS Versalloy™ XL- 9045-1 alloy in 45 Shore A durometer, an FDA-compliant medical TPV grade designed for overmolding onto PP.
