Microcellular Polyurethane

Toral has a record as a system for shoe soles in Japan by combining of polyol component HT+SM type/isocyanate component F type to to blend and mold shoe soles. The system is a urethane molding system by water foaming and the lineup features ether-based and ester-based systems for each hardness and density.

Microcellular Polyurethane

  • Excellent continuous productivity (small article molding)
  • Possess a stable microcellular structure
  • Capable of accommodating static control formulations with static blends

In addition to shoe soles, aiming to expand applications into the office equipment field.

Molding Flow
