Mounting Tape Said To Give Three Times the Thermal Conductivity of Competing Tapes

MH&W International has introduced Keratherm KL 90 highly thermally conductive, double-sided adhesive tape which provides 1.4 W/mK of thermal conductivity – said to be three times higher than other thermal tapes – for more effective heat transfer from hot components to heat sinks. The new tape’s thermal impedance is just 208°C-mm2/W (0.32°K-in2/W).

Keratherm KL 90 tape consists of a ceramic-filled acrylic adhesive film that provides exceptional bonding properties, and replaces the use of mechanical fasteners, reducing costs and assembly time. A fiberglass-reinforced version, KL 91, is available for applications requiring higher levels of ruggedness, peel strength, and conformability to irregular surfaces. Both Keratherm KL 90 and KL 91 mounting tapes are silicone-free, eliminating any contamination concerns. If necessary, the tapes can be cleanly removed using a thin-edge blade.

Keratherm KL 90 double-sided adhesive tape is supplied on 400 mm (15.75 in) wide rolls, and is also available in custom die-cut shapes. Its standard material thickness is 0.300 mm, (0.012 in). KL 90 tape pricing starts at $0.22 per square inch in high volume orders.
