Panacol has developed a new plastic bonder, Vitralit® UV 7030, certified to USP Class VI biocompatibility standards for medical device assembly applications, featuring high elongation at break, as well as excellent adhesion to difficult to bond plastics.
The various material selections and pairings of flexible tubing and rigid connectors often create significant assembly challenges in high volume production. Materials used to create infusion lines, catheters, and similar medical devices may include TPU, TPE, PEN, polyamides, Pebax®, polycarbonate, ABS and PEEK.
These thermoplastics and thermoplastic elastomers provide many desirable properties, but some combinations can be difficult to bond. After assembly, these materials are challenged by torsional stresses at the points of transition between the soft tubing and the hard connector. Panacol developed the adhesive Vitralit® UV 7030 to specifically address these complex issues.
Vitralit® UV 7030 is a one component, solvent free UV curable acrylic adhesive. It can be cured with light energy in the broad UV-A spectrum, or with LED systems that produce either 365Nm or 405Nm wavelength. This adhesive cures in seconds at layer thicknesses of a few 100µm, ensuring high bond strength immediately after UV exposure.
A key feature of Vitralit UV 7030 is its high elongation at break, >250%, combined with good tensile strength. When exposed to black light, Vitralit UV 7030 fluoresces, which enables visual process control. Vitralit UV 7030 is certified to USP Class VI standards and suitable for typical sterilisation processes including gamma, EtO and autoclave.
