Tek-Sil® GP

Gel Pads, Extra Soft Gap Fillers 

With a durometer of ≤5, our Tek-Sil® GP gel pads fill all voids.  Gel pads, which are made of unreinforced silicone rubber, are quite thermally conductive (1.5W/m-k).  They are so soft and tacky that no PSA is required.  To ease handling problems, the sheets have release liner on both sides.  "GP" is made in 9 thicknesses ranging from .020" to .197" (0.50- 5.0mm).  All thicknesses are supplied in sheets 11.8" x 7.9" (300 x 200mm). 


As with all other Tek-Sil® materials, Teknational will die cut special shapes to customer specifications.

To order sheets of "GP", specify the thickness

(Part Number GP-40 for a sheet .04" (1.0mm) thick).
