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.

Fortunately, there are several kinds of additives that don’t affect future recyclability of PET that can used during processing to correct for this yellowing. Similar to the ones that correct yellowing, there are special additives that “scavenge” or otherwise reduce the levels of acetaldehyde. In addition, chain extender additives can improve IV for better strength and performance.

Avient offers a comprehensive portfolio of colorants and additives for nonwovens in the form of concentrates. Custom color, additive or color/additive combination concentrates can be developed to meet the specific requirements of your application. Electret additives help retain the electrostatic charge on the polymer surface for for longer periods of time.

Lowered energy requirements versus painting and the reduction of VOCs also made this masterbatch a more environmentally sustainable solution.

Cesa™ WithStand™ Antimicrobial Additives Cesa™ WithStand™ Antimicrobial technologies counteract bacteria, fungi and microbes to enhance the performance of plastic products and devices. Cesa WithStand Antimicrobial Additives can be used across a wide range of polymer types. Cesa WithStand solutions include technical assistance to customize the additive dosage, as well as support with processes and specifications, helping to reduce time to market and saving time and cost in the development process.

Cesa™ Fiber Additives Antimicrobial Additives for Synthetic Fibers and Nonwovens Bacteria and other microorganisms can cause unpleasant odor, discoloration and even degradation of surface qualities in textiles and nonwovens. The Cesa™ Fiber Additives portfolio includes antimicrobial concentrates that help prevent these problems by limiting the growth of microorganisms. The additive concentrates are highly recommended for applications requiring long-term protection in textiles made of PP, PET, and PA.
