TekNational - Tek-Sil® GP

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 thicknbesses 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.

Material properties, comparative Thermal Resistance and Compression Set for all thicknesses are shown below.

To order sheets of "GP", specify the thickness

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