PolyOne compiles bonding, adhesion, and welding parameters for Versaflex grades for medical fluid delivery systems

The studies focused on bondability between Versaflex HC MT series TPEs and other materials, including various rigid plastics, metals and TPEs. Results of this initiative can help healthcare customers shorten development time and reduce testing costs for fluid delivery systems. To conduct the studies, PolyOne said that it has worked with industry leaders in this field, including:Henkel generated data on solventless adhesion of Versaflex TPEs to various thermoplastics (including polyamide, high- and low-density polyethylene, acetal, polypropylene, polybutylene terephthalate), as well as galvanized steel and aluminum. Henkel conducted immediate, 24-hour and seven-day bond performance tests on Versaflex HC MT tubing using a range of its Locktite adhesives (UV curable, epoxy, urethane, and others).Genesis Plastics Welding evaluated the use of their ecoGenesis process with the Versaflex grades. Solventless adhesion such as heat welding is becoming increasingly popular in healthcare as an alternative to bonding plastic materials.NDH worked with PolyOne to conduct internal solvent bonding tests of Versaflex with itself and with various substrates, including ABS, PVC and PC."Processors, device manufacturers and pharmaceutical companies have to determine which process is most effective for joining two materials," said Rick Noller, director of global marketing, PolyOne GLS Thermoplastic Elastomers. "By taking the initiative to conduct these bondability studies, PolyOne reduces the amount of experimentation and testing customers may need to perform, accelerating their time to market. Results and guidance from the bondability studies are available upon request at PolyOne.
