TekNational - Tek-Sil® GP4X

Tek-Sil® GP4X

High Performance Gel Pads

If you need a gap filler with higher thermal conductivity, Gel Pad "GP4X" is rated at 2.30 watt/mk compared to 1.5 watt/mk for the standard "GP" material. Thermal Resistance data and Compression Set for each thickness are shown below. This material is available in six thicknesses ranging from .020" to .118" (.50 - 3.00mm). Consult the plant for data on thicknesses greater than .118".

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 "GP4X", specify the thickness

(Part number GP4X-118 for a sheet .118" (3.0mm) thick).
