Advancell EM is thermal expandable microsphere with the thermoplastic cell containing low boiling point liquid hydrocarbon. When heated, Advancell EM microspheres expand greatly in size; the heat boils hydrocarbon while softens the thermoplastic shell and expands the shell.

Because it is a hollow balloon, it creates closed cell structure. By selecting the appropriate grade, you can optimize the expansion starting temperature or degree of expansion.

Applications -

  • It can be used in weight reduction and appearance improvement purpose for thermoplastics, inks, and coatings.
  • Structural Foam (EVA-EM, PVC, PP, PE, Epoxy, Rubber, Silicon, etc), Wall Paper, Sound Damping Coating, Clay, Shoes, and functional filler. It can be used as a mating agent as well.
  • Process It can be used in extrusion molding, injection molding, coating, and various other processes such as Press Molding, Blow Molding, and etc.
  • Characteristics of Thermal Expandable Microspheres
  • Characteristics of Thermal Expandable Microspheres After expansion, it creates very low-density micro-balloons with the following characteristics.


  • Fine, uniform, closed-cell structure
  • Expands even in low viscosity system
  • No surface pin holes
  • Cell size can be controlled by selecting the appropriate grade
