The long glass fiber reinforcement within the hybrid solutions offers a significant boost in toughness to the formulation, protecting your application from impact failure. You are still able to gain the strength of carbon fiber, but are also able to supplement a portion of the formulation with more economically priced glass fiber.  Application Development Center

CLEVELAND – 2019年8月5日 – PolyOne today announced availability of ColorMatrix™ Excelite™ IM chemical foaming additives (CFAs), formulated specifically for injection molding applications. New Excelite IM chemical foaming additives are suitable for use in automotive, construction, commercial, personal care packaging or structural foamed applications.  The company adds value to global customers and improves sustainability through formulating materials, such as:

This makes them a common choice for wire and cable aerospace applications. In addition, the unique formulation offers excellent processing thanks to reduced lump formation. Our history of providing high-performance solutions is demonstrated through our robust portfolio of fluoropolymer color concentrates and high-temperature formulations,” said Anne Hippert, general manager, Colorant Chromatics group at Avient.
