The graph of the heat conductivity versus the temperature of the neoprene NEOPORM® brand D 130
The ratio of thermal conductivity to temperature (ASTM C1045, p. X3.3.1):
λ(t)=0.0443+1.421·10-4·t+1.46·10-7·t2+2·10-10·t3
The values of thermal conductivity as a function of temperature (ASTM C177, C1045).
The values were determined in isolation by calculating the polynomial at an average temperature
