Dualite U024-145W and Dualite U024-145D are heat-expandable polymeric microspheres. These microspheres consist of an acrylonitrile copolymer shell that encapsulates a low-medium boiling point liquid.
Common Applications: When heat is applied, the microspheres expand to form a low-density, foamed layer in systems that incorporate these microspheres.
Type: Spheres
