ColorMatrix™ Optica™ Specialty Toners for PC Polycarbonate is used for the production of automotive interiors and appliances to consumer goods and electronics, replacing more traditional materials such as glass and acrylic. ColorMatrix™ Optica™ Specialty Toners for PC is the cutting-edge liquid toner for polycarbonate resins that provides visual clarity for PC and improves aesthetics on the product surface. This solution offers better color consistency and better color dispersion in transparent PC resins, helping to retain transparent properties and preventing contamination by keeping production lines clean.

CESA™ Light Additives Light Stability PRODUCT SELECTION GUIDE Exposure to the sun, heat, and oxygen through outdoor exposure causes the degradation of the polymer, resulting in yellowing, loss of melt strength, and loss of mechanical properties in most resins. CESA™ Light additives can protect the resin in multiple ways. It is effective at protecting the resin and, if needed, the contents.

CLEVELAND – February 3, 2025 – Avient Corporation, an innovator of materials solutions, today announced the availability of Cesa™ WithStand™ SX Low Haze Antimicrobial Additives for clear polycarbonate and plexiglass applications. This patent-pending next-generation formula is especially useful for products incorporating recycled resin. Traditional antimicrobials often cause opacity or hazing in polycarbonate or acrylic.

Their suitability spans various resins from polyolefins and styrenics to engineering resins. For use across a wide range of resins Cesa™ Flame Retardant Additives PTFE-free and Non-halogen for Polycarbonate

From engineered, man-made, or natural fiber reinforcements to thermoset or thermoplastic resins, there is a lot to consider when selecting a composite material. Thermoplastics used in making composites range from polypropylene (PP), nylon (PA) and polycarbonate (PC) to polyester, polyphenylene sulfide (PPS), and polyetheretherketone (PEEK).
