Polyurethane thermal expansion coefficient
WebPolyamide thermal break has a higher melting point than PVC or polyurethane used in other systems. Since its thermal expansion coefficient is very close to aluminum, the bond between it and the extrusion maintains excellent structural integrity through a wide range of temperature fluctuations. WebThermal Expansion of PUR Foams. PUR foam exhibits an insignificant level of anisotropic behavior which is shown by the dilatometer measurement. The CTE values are nearly the same in the y- and z-directions between -160°C and 100°C. An additional measurement was performed in each direction; the results also demonstrate the excellent ...
