KUREHA Microsphere

KUREHA Microsphere

KUREHA Microspheres are thermally expandable microcapsules developed by Kureha. They are used in a wide range of applications, including automobile components, footwear soles, foaming ink and adhesives.

Characteristics

  • Narrow temperature range from start to maximum foaming.
  • Size distribution is narrow, for uniform particles.

KUREHA Microspheres are consistent by grade, with a wide maximum expansion temperature of 120oC-210oC. We are currently developing a high heat-resistant grade with a maximum expansion temperature of 230oC-250oC for use in injection and extrusion molding.
