Hydrocerol™ Chemical Foaming and Nucleating Agents reduce material requirements by up to 20% without compromising stiffness, mechanical properties, or aesthetic appeal. These injection moldable TPEs can be overmolded to polypropylene (PP) and come in a natural grade that can be easily colored. More recently, with the divestiture of the PP&S segment in 2019 and the acquisition of Clariant Color 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.
