AI Technology TP 7205

TP7205 is an alumina filled, low bond strength thermoplastic film adhesive. It is designed for bonding heat-sink, component, and substrate. TP7205 has good thermal conductivity and is tacky at room temperature. The adhesive film typically can be used for most applications at temperature from -65 to 150°C. Customers must test the adhesive for their specific application to confirm its suitability.
