Available in North America, injection-moldable reSound™ R VX TPEs utilize 25% (PCR) and up to 40 percent (PIR) recycled content, and both grades can be overmolded onto polypropylene (PP). More recently, with the divestiture of the PP&S segment in 2019 and the acquisition of Clariant Masterbatch in 2020, we have fundamentally repositioned our portfolio to that of a true specialty enterprise—from which we can springboard to even greater heights in the future.

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.
