BEST VALUE
Tek-Sil® SCT is an unreinforced version of "SR" without the fiber glass matrix.  To provide puncture resistance, "SCT" is somewhat thicker than "SR" materials.  It is made in three thicknesses from .012" to .033".  The added thickness combined with the smooth surface of "SCT" make it a highly comformable material.  PSA is not available for the unreinforced materials.
