Silicone Free Thermal Pad: CPSH Series

Soft, 5W/m•K silicone-free thermal pad for high operating temperature applications.

  • Soft (ASKER C 32) silicone-free thermal pad.
  • Compilable thermal pad helps to crowd out air bubbles to reduce thermal resistance.
  • No siloxane outgassing or oil bleed.
  • Available in one side thin, permanent PET film and one side naturally tacky; and both sides naturally tacky.
  • Custom profile available upon request.
  • Operating temperature: -40 ~ 125˚C.
