Proposed performance for reuse

  • Thermal conductivity: 0.0295 W/mK

  • Compressive strength: ≥ 120 kPa

  • Dimensional stability: High risk of extreme expansion at high temperature (70°C) and high relative humidity (90%). No risk at low temperature (-20°C).

  • Water absorption: Possibly higher water absorption than the current limit value of 2 vol%.
