TPE Tubing Weld Testing

Bioflex tpe tubing.jpg

The ability to aseptically weld tubing is critical to numerous biopharmaceutical manufacturing processes. Meissner’s BioFlex® thermoplastic elastomer (TPE) tubing is designed to be both weldable and sealable, making it well suited for use in many applications requiring aseptic liquid transfer. This technical bulletin presents the results of BioFlex® TPE tubing weld testing.

To assess weld integrity, tensile testing was performed on gamma irradiated and autoclaved samples of welded BioFlex® TPE and C-Flex® 374 tubing. Testing was conducted for BioFlex® TPE welded to BioFlex® TPE, C-Flex® 374 welded to C-Flex® 374, and BioFlex® TPE welded to C-Flex® 374 to account for a degree of versatility in established processes. Elongation, force at peak, and Young’s modulus were measured for each of the tubing sample sets.
