LAIRD TFLEX HD90500

Main features

  • 7.5 W/(m K) Thermal Interface
  • Compliant Silicone Gap Filler
  • Naturally Tacky Construction

Product Description

Tflex™ HD90500 is a 500 um configuration within the Tflex™ HD90000 Series, a high-performance silicone thermal gap filler engineered for applications requiring efficient heat transfer and low mechanical stress on sensitive electronic components. The ceramic-filled silicone construction provides typical thermal conductivity of 7.5 W/m·K while maintaining high compliance for effective contact across uneven mating surfaces. Naturally tacky surfaces support placement during assembly without requiring an additional adhesive coating.

Key features

  • 7.5 W/m·K thermal conductivity for demanding electronics cooling applications.
  • Highly compliant silicone construction helps minimize stress while conforming to uneven surfaces.
  • Naturally tacky surfaces simplify installation without an additional adhesive layer.

Applications / Suitable for

  • Automotive electronics and ADAS modules
  • High-performance computing and networking equipment
  • Industrial power electronics
  • Telecommunications infrastructure

Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
7.5 W/m.K
UL 94 Rating
Flammability rating classification. It determines how fast a material burns or extinguishes once it is ignited. HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed. V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed. 5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole. 5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole

Electrical Properties
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
