Silicone‐Free Thermal Pad: CPVS Series

Soft (ASKER C 18) silicone-free thermal pad
Many optical, medical, and sensor applications cannot allow silicone particles to be located within their enclosures. To meet the needs of these industries, KITAGAWA INDUSTRIES America offers a line of non-silicone based thermal pads/Thermal Interface Materials (TIM) to eliminate any worries regarding siloxane gasses. These are available in thermal conductivity between 2.0 W/m*K. Like silicone based thermal pads, self-tackiness on both sides and one side self-tackiness are available as options. Available thicknesses range from 0.5 – 2.0 mm.

  • Excellent stress relaxation property reduces the stress on the elements after mounting.
  • Silicone-free material – no siloxane outgassing or extraction.
  • Overall low outgassing.
  • Suitable for vibration control as well.
  • Highly conformable, low contact thermal resistance.
  • Operating temperature -40 ~ 100°C
