TekNational - Tek-Sil® SB Materials (OPTIMUM PERFORMANCE)

Tek-Sil® SB Materials

Tek-Sil® "SB" is our best performing material with thermal conductivity measured at 2.9 watts/m-k and thermal resistance as low as .10°C. It is available in four thicknesses from .008"(.20) to .033"(.85). All "SB" materials are coated on a fiber glass matrix to improve tear strength and prevent pin holes from forming. These materials also have excellent dielectric strength. They are available with optional PSA.
