THERM-A-GAP PAD 80 – Thermally Conductive High Performance Gap Filler Pad

Parker Chomerics THERM-A-GAP PAD 80 is a high performance, thermally conductive gap filler pad with a thermal conductivity of 8.3 W/m-K. It provides superior heat transfer across a range of thicknesses while maintaining low compression forces and conformability between mating surfaces.

THERM-A-GAP PAD 80 is designed to serve as an effective thermal interface between heat sinks and heat generating components on electronic devices where uneven surfaces, air gaps, and rough surfaces may exist. This material exhibits low silicone oil bleeding and is ideal for high thermal performance needs across industries.

THERM-A-GAP PAD 80 is available in standard thicknesses from 0.020” to 0.200” (0.50mm to 5.1mm) and can be provided in sheets or cut to custom part sizes. It is available on several material carriers including an aluminum foil carrier that is supplied with pressure sensitive adhesive (PSA) for added adhesive strength during the assembly process.

For applications where lower thermal conductivity is sufficient, we recommend the lower-cost variants PAD 60 and PAD 30.
