  • The ratio based on the best value varies with the type and quantity of added paint additives.
  • The free rise foam density varies with the seasonal variation (temperature, humidity)
  • These physical data are acquired by testing a sample of 6mm thick.
  • Data listed above are just for reference. The detailed data are subjected to practical operation. Please contact us if other physical properties are essential.
