Tflex

P300 Series

Polyimide Lined Gap Filler

Product Description

Laird Tflex® P300 is a soft and compliant gap filler with an integrated polyimide liner. Laird

has leveraged its vast experience and knowledge in the development of thermally conductive

materials to develop a soft and compliant gap filler that minimizes contact resistance and

board level stresses. In conjunction with these key traits Laird understands that not all

applications are the same. As a result, Tflex P300 comes with a unique and integrated polyimide

film on one side. This liner provides numerous application benefits like electrical isolation,

placement ease during assembly, and tear resistance for applications that require shear.
