Black polyimide film strips on carrier sheets, 50 pieces 10 by 60 mm, 30 µm thick

Thermal Grizzly

Thermal Grizzly Kapton Insulation Sheet Black Edition 50 strips 10×60 mm 30 µm

SKU CH-QF20-WDG3F

Polyimide film masks SMDs during liquid-metal application, withstands 260 °C and insulates beyond 5 kV with 50 pre-cut 10×60 mm strips at 30 µm thickness

  • Withstands 260 °C for liquid-metal installs
  • 30 µm film fits tight component gaps
  • 5 kV breakdown voltage blocks short circuits
  • 50 pre-cut 10×60 mm strips speed masking
  • Polyimide base resists tearing during handling

Kapton Black Edition for Liquid Metal

The Thermal Grizzly Kapton Insulation Sheet Black Edition is a polyimide film designed to mask sensitive components during liquid-metal application. It protects SMDs on CPUs and GPUs when using electrically conductive TIMs such as Conductonaut or Carbonaut. The pack contains fifty adhesive strips sized 10 by 60 millimetres. Builders handling liquid metal will find it essential for preventing short circuits.

High-Temperature Resistance and Dielectric Strength

Each strip is 30 micrometres thick and withstands continuous temperatures up to 260 degrees Celsius. The material provides a breakdown voltage exceeding 5 kilovolts, offering reliable electrical isolation under load. Compared with the standard 40-micrometre sheet, this Black Edition is thinner while delivering superior dielectric performance. Surfaces should be cleaned with isopropyl alcohol before application for best adhesion.

Fifty Pre-Cut Strips on Carrier Foils

The product ships as ten carrier foils, each holding five ready-to-use strips. No cutting or measuring is required, which speeds up installation and reduces waste. Buyers who need custom shapes or larger continuous sheets will need a different format. The pre-cut layout suits repetitive masking tasks on identical component footprints.

Questions about this item

How do I install the 30 µm Kapton strips on a CPU or GPU without trapping residue?

Clean the surface with isopropyl alcohol, peel each 10×60 mm strip from its carrier foil, and press it firmly over the SMDs you want to mask before applying liquid metal or other conductive TIM.

Will the adhesive on these polyimide strips degrade after repeated heating cycles up to 260 °C?

The film is rated for continuous use at 260 °C; the adhesive remains stable at that temperature, but the strips are intended for single installation and should be replaced if removed.

At what voltage will the 30 µm Black Edition insulation break down during sustained liquid-metal contact?

Breakdown voltage exceeds 5 kV, so the 30 µm layer reliably blocks electrical shorts from conductive TIMs under normal operating conditions.
