Silicone Thermal Gap Filler Gaskets

Atlantic Gasket Corporation, a leading manufacturer of custom gaskets, die-cut parts, and adhesive-backed tapes, offers an extensive selection of silicone thermal gap filler gaskets. These high-performance silicone rubbers create a highly efficient thermal pathway between heat-generating components and their heat sinks, replacing inefficient air gaps. By filling these gaps, the silicone thermal gap fillers optimize heat transfer and ensure reliable performance across various applications.

Silicone thermal gap fillers are domestically produced, UL94-V0 rated, and come in thicknesses ranging from 0.5mm to 5mm. Available in multiple hardnesses (Shore 00 durometer) and thermal conductivities (1 W/m·K, 1.8 W/m·K, 2 W/m·K, 3 W/m·K, and 5 W/m·K), these gap fillers can withstand temperatures from -60°C to 200°C (-76°F to 392°F). Silicone gap fillers are ideal for use in a wide array of industries, including:

  • Automotive/Electric Vehicles (EV)
  • Aerospace
  • Battery and Power Converters
  • Consumer Electronics
  • LED Lighting
  • Solar Energy
