For the purposes of this Sustainability Report, data and content, unless otherwise noted, include that of PolyOne’s Performance Products and Solutions (PP&S) business segment, which we have recently announced an agreement to divest. Custom products can be formulated with recycled PP and PE for improved recyclability, plus the portfolio includes halogen and non-halogen products. In addition to on site renewable energy installations, PolyOne is actively working to procure energy from green sources in an effort to reduce its greenhouse gas intensity.

The injection-moldable Versaflex™ HC 3810 series is formulated without animal derivatives and offers a wide range of durometers to serve a variety of medical device applications.  

Benefits of Hydrocerol™ Chemical Foaming Agents They are endothermic chemical foaming agents that provide the following benefits in the injection molding process: Chemical foaming agents versus other technologies PP T20 with physical foaming agent (PFA), large cell structures, thin outer cover layer PP T20 + 3% Hydrocerol concentrate, small cell structures, thick outer cover layer Photo source: Neue Materialen Bayreuth (GmbH) During the activation reaction, chemical foaming agents principally react in two ways: • exothermic • endothermic Exothermic CFAs release more energy during decomposition than needed for the reaction.
