Open structures, plants using flammable

Design liquid storage so leaks and spills do not accumulate under tanks or process equipment Use open structures for plants using flammable or combustible materials Avoid buried tanks...

Silicone foam thus formed has an open cell structure and is a relatively poor insulating material. Cell size can he controlled by the selection of fillers, which serve as bubble nucleating sites. The addition of quartz as a filler gready improves the flame retardancy of the foam chat yields of >65% can he achieved. Because of its excellent flammability characteristics, Silicone foam is used in building and construction fire-stop systems and as pipe insulation in power plants. Typical physical properties of silicone foam are listed in Table 10.
