About Devinall TH & THB

Devinall TH and THB Thermally Conductive Polyimide Films offer 4 times the thermal conductivity and cut thru strength than our standard Devinall SP Series.  These enhanced characteristics allow Devinall TH & THB to be a viable solution for an array of applications including dielectric/insulating thermal interface materials, insulating layer/shim, heat management and insulation within electronics assembly, printed circuit boards and automotive applications (due to resistance to handling and wear).  Devinall TH and THB offer reliable thermal transfer and high dielectric strength when cooling of a non-insulated heat dissipating devices is required.

More Information and Samples

Material evaluation is always critical when designing in a new material or developing a new product.  Sheet samples or Devinall SP or TH Polyimide Films are available for preliminary review and testing to determine the optimal FastelFilm formulation, thickness, setup and heating method within the scope of your application requirements.

Want to Test Samples First Per Your Required Outline?

Our razor plotter sampling machine allows us to provide our customers Devinall already cut to their required outline for testing.  Plotter formed samples provide our customers the ability to test not only the Devinall, but their required outline as well without incurring the expensive of production tooling.  The ability to plotter cut samples is dependent on the required customer die cut outline needed.   For more information to see if your required die cut can be plottered first for sampling, please e-mail
