Genesis Plastics Welding and PolyOne collaborate on RF welding

Facing environmental and health concerns with traditional materials, manufacturers of medical fluid delivery products are looking for alternatives that avoid the use of halogens and plasticisers. A breakthrough technology from Genesis enables non-halogenated and non-plasticised GLS Versaflex TPEs to be RF welded into any two-dimensional shape or configuration, including mandrels.Collaboration between Genesis and PolyOne expands the portfolio of Versaflex grades that can be welded using ecoGenesis technology to provide the market with a solution for fluid delivery applications, including better flexibility, mechanical properties, clarity, aesthetics and value. Prior to this development, older RF welding techniques were restricted to high dielectric loss materials and TPEs could only be heat sealed, limiting configurations to straight lines.The ecoGenesis technology enables non-phthalate, low dielectric loss material to be RF welded. Applications for ecoGenesis RF-welded Versaflex TPEs include infusion kits, blood transfer and drainage bags, and urinary bags."Changes in environmental and medical device regulations are highlighting the many advantages of TPEs for healthcare applications," said Rick Noller, director of global marketing, PolyOne/GLS. "Through our work with Genesis, our Versaflex TPEs can better meet the needs of the medical device industry. We have validated ecoGenesis welding for use with Versaflex CLE and Versaflex MT220 grades, providing the industry better choices for the next generation of fluid delivery products.""With ecoGenesis, manufacturers can use materials such as PolyOne's Versaflex TPEs in RF welding just like PVC, often providing improved cost savings and a more environmentally friendly product," said Tom Ryder, president and chief executive officer for Genesis Plastics Welding.Versaflex TPEs are more flexible than polypropylene, autoclavable unlike polyethylene, and have a good tear strength. The products also deliver very good clarity and a fine, matte finish. Further, thinner gauges of Versaflex TPE can provide the same feel and texture as thicker gauges of traditional materials, thereby lowering system costs.About Genesis Plastics Welding
Genesis is a plastics welding contract manufacturer specializing in the radio frequency (RF) welding of thermoplastic products and components for industries including medical, military, automotive, marine and consumer products. Unique to the plastics welding industry, Genesis' proprietary heat sealing technology allows RF welding of polyethylene, polypropylene and nearly any low-loss polymer in film, foam and fabric layers. The technology is ideal for the replacement of PVC and polyurethane with "green", phthalate-free plastics as it causes polymers with low dielectric loss factors to respond to RF welding just like PVC. The company's plastics welding technology, ecoGenesis, also aids in cost reduction as it eliminates the need for expensive heat seal additives, accelerates the production process and enables the substitution of lower cost raw materials. Available for private licensing to manufacturers, ecoGenesis can be integrated into any existing RF heat sealing machine.
