TekNational - Tek-Sil® GPH

Tek-Sil® GPH

Gel Pads, Extra Soft Gap Fillers

In some assembly situations, the stickiness of our standard Gel Pad "GP" makes it difficult to handle. We now offer gel pad "GPH" which is hardened on one surface. Even with the hardened surface, this material is supplied with release liner on both sides. Thermal characteristics are not affected by the hardening. Shandard sheet sizes and thicknesses are available.

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 "GPH", specify the thickness

(Part number GPH-197 for a sheet .197" (5.0mm) thick).
