Product Description: Aeroflex Closed Cell Tube and Sheet Insulation is a flexible, closed cell and lightweight elastomeric material designed for insulating liquid cooling and heating lines. The closed cell structure of Aeroflex provides many advantages over most rigid insulations for cooling and heating lines, such as: A: Moisture & vapor resistance without using additional vapor barriers. B: Stable thermal conductivity (K. value) during service, due to its dense surface skins and closed cell characteristics. C: Outstanding ultraviolet and weather resistance Product Feature * Standard sheet is avaiable in size of 36"*48"*(1/8"~2¡°)and 0.5m*0.2*(3mm~50mm).it prevents heat loss and condensation on large pipelindes, tanks, chillers, air duct, other irregular shaped vessl * Low thermal conducutivity (K.value). eg.: Ë=0.032-20 Ë=0.0340 Ë=0.03940 * Stable thermal conductivity (K.value) during ervice,sue to its dense surfaceskins and closed cell characteristics. * Heat stability(6% shrinkage ) 93 7days * Moisture &vapor resistance without using additional vapor barrieris. Water vapor permeability within 0.10;Mositure resistance Ì>=10000;Water absorption
