Silicone-free thermal gap filler can be used on gaps down to 0.5mm

Silicone-free, low-viscosity and described as easy to dispense, Sarcon SPG-25B-NS exhibits a thermal conductivity of 2.5 W/m degrees K and a thermal resistance of only 2.1 degrees K•cm2/W. Fujipoly says that ehen applied between heat-generating components and a nearby heat sink or spreader, the form stable thermal material completely fills delicate gaps as small as 0.5mm. This allows for more efficient transfer and dissipation of heat from the component to enhance performance.

SPG-25B-NSA is claimed to have “excellent vibration absorption capabilities” and does not require heat curing. It will not cause corrosion on metal surfaces, and maintains all initial properties across a wide temperature range of -40 to +120 degrees C, adds Fujipoly. As a result, SPG-25B-NS is suitable for smaller electronic devices and higher frequencies. The gap filler is available for order in 30cc syringes or 325cc cartridges. Custom packaging is also available upon request.
