Tflex P300

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.

Features and Benefits
  • Compliant nature minimizes contact resistance
  • Integrated polyimide film provides dielectric strength
  • Resistance to burrs and mechanical forces
  • Resistant to shear forces.
  • Thermal Conductivity of 3 W/mK
  • Contrasting color allows integration with vision system
  • Low silicone bleed
