Silicone Putty


Laird Technologies, Inc.  announces it has expanded its thermal gap filler product line with the release of its Tputty™ 506 series silicone putty.

Specifically designed for high-wattage electronic applications, including automotive components, Tputty™ 506 is a soft, single part, silicone putty thermal gap filler in which no cure is required. With a thermal conductivity of 3.5 W/mK, it is ideal for situations involving large gap tolerances and in instances where traditional gap filler pads cannot be applied due to low pressure tolerances of the affected parts.
“Tputty™ 506 is a practical thermal gap filler material in that it is dispensed to specifically fill large and uneven gaps in assemblies,” said Jane Bell, Laird Technologies Thermal Interface Materials Product Manager. “It is non-abrasive, which leads to less wear on the dispensing equipment.”

The silicone putty material transfers little to no pressure between interfaces. Because it is more viscous than grease, bleed and pump-out usually associated with grease is eliminated. Highly conformable and reworkable, Tputty™ 506 is colored for automatic detection systems and is available in 75cc, 180cc, 360cc and 600cc cartridges, and also 20kg buckets.
