Tflex CR350

Two Part Liquid Dispensable Gap Filler

Product Description

Tflex CR350 is a soft, compliant, high thermal conductivity, two-part dispensable gap filler providing a low thermal resistance and high reliability. This dispensable gap filler minimizes stress on components during assembly while providing the reliability of a traditional thermal pad. Tflex CR350 is ideal for application where large gap tolerances are present, meeting vertical shock and vibe requirements, typical of the automotive industry. The 1:1 mix is easily dispensable through a wide variety of off the shelve dispensing equipment. It is an A+B putty material that cures in place after dispensing and mixing to perfectly fill the gap. The experts at Laird can help design the system that is right for you
