Low Compression Set, Thermally Conductive
Silicone Sponge


 

Product Description:
Thermally Conductive Silicone Sponge 72-TCD series is a thermally conductive closed cell silicone sponge rubber. This material offers thermal conductivity along with electrical isolation. It has excellent conformability to irregular surfaces and a clean release from most materials. Available in multiple thicknesses to fill various air gap heights. Its cellular structure provides extremely compliant gap filler.
This material is recommended to fill the needs of an unsupported thermal transfer material in applications requiring clean release, enhanced thermal performance by filling air gaps, electrical isolation and vibration cushioning.
  Common Applications: Gasketing and cushioning applications requiring critical thermal transfer and sealing. It can also be used for seals, press pads, computers, telecommunication, automotive electronics, military, medical, heat pipe assemblies, CD ROM cooling, thermal insulating, thermal shielding, heat transfer, decal transfer, print presses, and vibration mounts.   Discounts on orders of $1000, $5000.
