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 a GLS™ Versalloy™ alloy in 45 Shore A durometer, an FDA-compliant medical TPV grade designed for overmolding onto PP.

While polypropylene (PP) is widely accepted in the packaging industry, it has higher shrinkage rates than ABS, making it challenging to use as a direct replacement for existing molds.   To enable customers to use their existing ABS molds, Avient has developed new PP-based grades with comparable shrinkage to traditionally used ABS materials.

If local and regional customers require, these Complēt and OnForce formulations can be tailored to meet specific application requirements by utilizing a range of engineering resins, from polypropylene (PP) and acrylonitrile butadiene styrene (ABS) to polyphenylene sulfide (PPS) and polyphthalamide (PPA) for power tools, sports equipment, utility vehicle, furniture, and outdoor recreation applications.
