Mevopur™ Healthcare Functional Additives Laser Welding Additives for Medical Devices Laser welding has become a technology of choice to join plastic parts of complex medical devices. Avient uses a “systems approach” to develop the laser welding solution most adapted to your project, taking into consideration the following aspects: • Transmitting and absorbing parts • Polymer type and grade • Dispersion of the additive in the final part • Sufficient and consistent loading of the additive • Part design: attention to flow separation at the welding interface • Color and opacitiy • Quality control – e.g. establish suitable control parameters (UV Visible Spectra) • Laser wavelength and processing parameter Mevopur™ Healthcare Functional Additives formulated for laser welding are designed for use in healthcare applications. KEY CHARACTERISTICS • Manufactured at four ISO 13485 certified sites, providing global consistency and increased security of supply • Documented change control beyond CAS number, reducing risk of change • Available as additive concentrates, ready-to-use additive formulations or ready-to-use additive/ colorant formulations for different polymers REGULATORY SUPPORT • Raw materials tested to: - ISO 10993-1 and USP biological evaluation - European Pharmacopeia 3.1.3/3.1.5 (polyolefin) - USP (polyethylene) - ICH Q3D elemental impurities • Registered Drug Master File (Type III) and/or Device Master File • Food contact established with FDA/EU* APPLICATION BULLETIN * FDA/EU compliance information available upon request; exceptions may occur Healthcare use limitations apply—see below.
