PRODUCT DESCRIPTION

A 7 W/m-K, extremely soft Gap Pad with exceptional thermal performance at low pressures.

BERGQUIST GAP PAD TGP 7000ULM is an extremely soft gap filling material rated at a high thermal conductivity of 7.0 W/m-K. 

It is specially formulated for high performance applications requiring low assembly stress. 

The material offers exceptional thermal performance at low pressures due to the unique filler package and ultra low modulus resin formulation.

BERGQUIST GAP PAD TGP 7000ULM is highly conformal to rough or irregular surfaces, allowing excellent wet-out at the interface. 

Protective liners are supplied on both sides allowing for ease of use.
