Tek-Sil® SQ Materials
Tek-Sil® SQ Material
Offered in three thicknesses ranging from .30 - .85mm, Tek-Sil® SQ is a medium firm material. With a durometer of 55, it may be used as thermally conductive gasketing which will absorb shock. It can also be squeezed into tight places. Tek-Sil® SQ's thermal properties are very good with conductivity measured at 1.10 W/m-k. Dielectrically, it will withstand a minimum 9KV depending upon thickness.
