PARIS — January 21, 2025 — At Pharmapack 2025, Avient Corporation, an innovator of materials solutions, will highlight its range of colorants and additives for supporting medication identification, promoting brand differentiation, and enhancing the performance and sustainability of medical devices and pharmaceutical packaging.
Mevopur™ Healthcare Bio-based Polymer Solutions — to help reduce carbon footprint, this range of color and additive concentrates are formulated with bio-based polypropylene, polyethylene, polycarbonate, acrylonitrile butadiene styrene, and styrenic polymers, offering significant carbon footprint reductions of 70% to 120% compared to their fossil-fuel-based counterparts, and manufactured under the same quality management system as other Mevopur products, they are drop-in solutions that can be used like their fossil-fuel-based counterparts in the injection molding, blow molding, and extrusion of medical devices and pharmaceutical packaging
Mevopur™ chemical foaming agents — to reduce material use by up to 20% depending on part geometry and wall thickness, these biocompatible chemical foaming solutions are suitable for the injection molding and extrusion of polyolefins, styrenics, and copolymers

Spin-dyeing (also known as dope-dyeing) solutions are often easier to process but don’t always reach the same jetness as bath-dyeing.
Renol deep black colorants are provided as color concentrates, also known as masterbatches, which are added to the polyester pellets during fiber extrusion in the spin-dyeing process.
