The High-Quality Expansion Effect

  • Independent micro-balloons result in a high-quality finish not offered by other chemical foaming agents.
  • Fine, uniform micro-balloons achieve a smooth surface.
  • The sharp particle size distribution achieved by Sekisui’s proprietary technology allows the micro-balloon size to be controlled.
  • Micro-balloons can be formed even in low-viscosity compositions.
