DOWSIL™ TC-4040 Dispensable Thermal Pad

A two part, 1:1 mix ratio, 4W/mk thermal conductivity silicone gel. It’s printable or dispensable to cure as a soft thermal gel to replace fabricated thermal pad for thermal transferring, stress relieving and shock damping. It could also be used as gap filler with reworkable performance. 

Uses:

  • Telecom power units and other industry power units that require 4W/mk thermal conductivity
  • Telecom equipment, e.g. base stations, optical transmission equipment, Ethernet switches/ routers
  • Datacom equipment, e.g. high speed solid-state disks (SSD) 

Benefits:

  • Better heat dissipation performance than equivalent 4W/mk fabricated thermal pads due to better wetting performance with interface
  • Lower total ownership of cost than fabricated thermal pads
  • High reliability of thermal and mechanical performance
  • Excellent slump resistance 
  • UL listing: UL 94 V0

Easy-to-dispense gap filler with strong thermal conductivity and slump resistance for efficient assembly

Are you trying to meet the demands of 5G technology, such as the demand for strong thermal conductivity? 5G designs require greater power densities, which produce greater heat. Technology with such high temperature output requires materials that help dissipate the heat, materials like DOWSIL™ TC-4040 Dispensable Thermal Pad.

DOWSIL™ TC-4040 Thermal Pad is a two-part thermal interface material (TIM) and gap filler that is easy to dispense and provides strong thermal conductivity. This material increases assembly efficiency by allowing for either room temperature or accelerated curing as well as vertical assembly before curing because of its excellent slump resistance. Thus, DOWSIL™ TC-4040 Dispensable Thermal Pad not only enables your 5G technology to function but optimizes the process by which that technology is assembled.
