Thermal expansion is independent of vol% density and matches that of solid … WebDec 1, 2014 · Closed porosity is an exellent property for thermal insulation since it prevents the convective component of heat transfer. But because of the high mass fraction (solid component of the foam), thermal conductivity is not significantly reduced. Increasing the porosity (which may be achieved by reducing the green density or reducing the sintering ...
WebAnother key property of anti-static foam is that it has a shelf life when exposed to the environment. Thus it is usually used as a one-time foam for shipping components. It is the least expensive type of ESD foam. It has a surface resistance of 10^9 to 10^10 Ohms or less (the higher this number the more slowly a charge is dissipated). ...
