KUREHA Microsphere　H1100-S

  • H1100-S has unique expansion characteristics.
  • Expansion start temperature (Tstart) drops if exposed to a pre-heating or heat treatment. This allows for maximum expansion performance in process.
  • Recommended pre-heat condition is 2 to 5 minutes between 150-170℃.
  • If used in molding/extrusion the cylinder should provide sufficient temperature.
  • In order to optimize H1100-S, it is recommended to process after heat treatment for maximum performance.
