The RTF7000 variable density foam system is a multi-component product which allows end-users to design finished foam products with a wide range of density, cell structure and physical properties based on the requirements of the end-use application. The system consists of a base, a crosslinker, and an additive that are mixed in various combinations and ratios to yield a cured silicone foam over a density range of 5 to 16 pounds per cubic foot. The RTF7000 variable density silicone foam system can be considered for a variety of applications where fire retardency, thermal insulation and low density are key considerations.
