Henkel Loctite Formulates New Innovative Thermal Absorbing Films

Henkel-Loctite-TAF-films The new series of novel thermal absorbing films are developed to address heat management challenges associated with high performance handheld devices.

Handheld device manufacturers strive for a skin (external housing) temperature – generally driven by the CPU heat output – of 40 degrees Celsius or less. Conventional thermal management solutions such as heat spreaders, heat sinks and graphite films have traditionally been employed, but with product dimensions becoming tighter, these solutions are often too large, thick or brittle for today’s handhelds.

Henkel’s Loctite TAF films resolve these challenges, delivering a thermal solution that has been proven to lower CPU and skin temperature of handhelds by over 3 degrees Celsius. The patent-pending materials offer a unique approach to heat management through their ability to absorb, spread, insulate and dissipate thermal energy generated by ICs.

“Managing the intense heat generated by today’s handheld products is one of the biggest challenges facing device designers today,” explains Henkel’s Jonathan Rowntree, Vice-President of Global Product Management. “While there are current solutions, they are limited in scope and can’t offer the contourable construction that will be required for next-generation device geometries.”

In passive applications with limited space for fans and heat sinks, thin, flexible film-based mediums are the ideal solution. When Loctite TAF material is placed in contact with the heat source, the material creates an airflow path, through which hot air is forced out of the device. Henkel’s unique thermal absorbing film is also dynamic, enabling regulation of heat and management of the CPU temperature rise and fall.

Loctite TAF thermal absorbers are available in customized, pre-cut sizes and thicknesses to accommodate specific application requirements. Immensely versatile, the film thickness and layer constructions can be adapted to create thinner or thicker solutions with multi-axis contourability, enabling orientation over and/or under components. Because the Loctite TAF films are bendable, they offer a more flexible solution for tight spaces as compared to conventional heat management materials which are often brittle and cannot adapt to device architectures.

“Henkel is constantly pushing beyond conventional industry approaches to enable future technology,” says Rowntree in summary. “Our team recognized the need for a robust, flexible response to traditional thermal materials used in passive devices and delivered Loctite TAF films well ahead of market requirements.”
