Thermal interface material (TIM) 1150 series

Thermal interface materials (TIMs) are designed to fill in air gaps and microscopic irregularities, resulting in dramatically lower thermal resistance and thus better cooling

Thermal interface material is used to fill the gaps between thermal transfer surfaces such as between microprocessors and heat sinks, in order to increase the efficiency of thermal transfer. There is usually air in these gaps, and air is a notoriously poor conductor. The interface material is easy to handle and is not messy. It is available in solid and liquid form and comes in various thicknesses.

Thermal conductivity

The thermal conductivity of the interface material determines its thermal performance to a large extent. The high thermal conductivity of this product guarantees sufficient heat transfer, resulting in a better cooling solution and the desired heat dissipation.


  • Good insulation properties
  • Heat conducting
  • Good compressibility
  • Flexible
  • Environmentally friendly


  • Smooth surface
  • Very good thermal transfer properties even at minimal contact pressure
  • Low hardness
  • High self-adhesion
  • UL listed
  • Thicknesses of 0.01 to 8 mm

This film, wih its excellent thermal and electrical properties, is especially suitable for high-power applications. The material performs so well that it can be used reliably in densely packed electronic applications.
