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.
