High-Density Silicone Elastomer

SF-150NH is a high-density two-part silicone elastomer, originally available from Brand Insulation Services (BISCO), now manufactured exclusively by PCI-Promatec. The SF-150NH provides a high degree of gamma radiation shielding, supplied at a minimum density of 147 FT?. SF-150NH is also an excellent flood seal material (up to 40 psi pressure - Ref M-179) Further, relative to other sealants, this material acts as a heat sink, (thereby reducing the concern for cable derating). Installed as a liquid, by hand or machine this ensures a complete fill in and around penetrating elements. Cured, it exhibits a durable, damage-resistant exterior rated excellent for decontaminability.
