TekNational - Tek-Sil® SA Materials

Tek-Sil® SA Materials

Formulated to provide clean release from most surfaces
Material is rigid enough to be easily die cut
Gap filler can be readily repositioned

Tek-Sil® SA is an unsupported, thermally conductive silicone rubber with high dielectric strength to protect against power surges. Tek-Sil® SA conforms better than many thermally conductive materials while protecting assemblies from mechancial shock and absorbing thermal expansion
