PolyOne develops new technology in welding Versaflex TPEs in medical application

PolyOne GLS Thermoplastic Elastomers, a specialist in high-performance, custom-formulated thermoplastic elastomers (TPEs), has developed a breakthrough in radio frequency (RF) welding in conjunction with Genesis Plastics Welding, a leading contract manufacturer of RF welded products.

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 plasticizers. For the first time, a technology from Genesis enables non-halogenated and non-plasticized 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.
