Tek-Sil® SR Materials
BEST VALUE
Tek-Sil® SR materials offer an economical solution to most thermal transfer problems. They are inexpensive and easy to use.  All Tek-Sil® SR materials are made with a fiber glass matrix to resist puncturing and improve tear strength. Tek-Sil® SR materials come with and without adhesive and can be die-cut or kiss-cut to specification.  "SR" is available in five standard thicknesses (.006" to .012") both with or without PSA.  Typical thermal conductivity for "SR" is .90 W/m-k.
