In addition, former metal products consisting of several parts can often be consolidated into a single, net shape to reduce assembly costs. And because they are thermoplastic, these CFRTP materials are more easily recycled compared to thermoset materials. Knowing that the judgments and decisions we make as individuals affect the way PolyOne is viewed in the marketplace and in the communities where we work, we let our personal values of Integrity, Honesty and Respect shape the way we do business.

Wire insulation, for example, requires a very different solution than film, tubing or profile shapes. Protective Materials Explore our portfolio of engineering materials for a wide variety of applications
