Welding, TPE suppliers join forces

The union of RF welding and material technologies will allow thermoplastic elastomers (TPE) to be joined via welding, opening up medical-market opportunities in fluid-delivery applications, including bags, tubing, and more. 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. Polyvinyl chloride (PVC), which has been traditional in fluid-delivery applications, has been under increased scrutiny over concerns with halogens and plasticizers.

The collaboration between Genesis Plastics Welding and PolyOne expands the portfolio of GLS Versaflex grades that can beNF_1013_PolyOneGenesis.jpg

welded using ecoGenesis technology, allowing flui- delivery applications that have better flexibility, mechanical properties, clarity, aesthetics, and value. Potential applications can infusion kits, blood transfer and drainage bags, and urinary bags

Polyone says its GLS Versaflex TPEs are more flexible than polypropylene (PP), autoclavable unlike polyethylene, and have better tear strength than competitive materials. These products also have clarity and a fine, matte finish. In addition, thinner gauges of Versaflex TPE can provide the same feel and texture as thicker gauges of traditional materials, thereby lowering system costs. —[email protected]
