Thermal Interface Solutions
As an industry leader in high-performance, cost-effective Thermal Interface Materials (TIMs) and technologies,
Laird designs and manufactures thermal products; including gap fillers and putties, phase change materials,
thermal grease, and thermally-conductive insulator materials that meet the demands of any application.
Meeting Ever-Increasing Thermal Demands
Today’s electronics are smaller and more powerful than ever before, leading to ever increasing thermal challenges
for the systems designer. While fans, heat sinks, and even liquid cooling and thermoelectric devices can be used to
provide enough cooling power, the problem remains transferring the heat from the hot components into the cooling
hardware. TIMs are designed to fill in air gaps and microscopic irregularities, resulting in dramatically lower thermal
resistance and thus better cooling. Laird is the world leader in material development for TIMs and offers the broadest
line of products to meet every design challenge. With gap filler pads, dispensable gap fillers, electrically insulating
and electrically conductive pads, Laird’s thermal interface products can solve any TIM design challenge. In addition,
Laird provides phase change TIMs that soften and fill tiny gaps at operating temperature, as well as thermally
conductive greases that conform to any surface irregularity. Laird’s thermal interface materials offer operating
temperatures up to 200°C, thermal conductivities over 8 W/mK in the Z axis, and tremendous flexibility in form factor
and packaging to support any manufacturing scenario.
Thermal Interface Materials
Gap Fillers
(Tflex
TM
, Tpli
TM
, Tputty
TM
)
Laird gap fillers are used to bridge the interface between hot
components and a chassis or heat sink assembly to increase the
overall heat transfer from the system. The unique combination of
thermal conductivity and softness reduces mechanical stress while
maintaining thermal performance. Laird’s extensive gap filler product
lines includes a wide range of performance capabilities, including ultra-
thin gap fillers, a high deflection series, and materials that provide
electrical isolation.

Dispensable Gap Fillers
(Tflex
TM
and Tputty

)
Laird dispensable gap fillers are used to bridge the interface
between hot components and a chassis or heat sink assembly when
elimination of mechanical stress or bulk automated dispensing are
critical design considerations. These materials can be dispensed to
fill large and uneven gaps in assemblies and due to their super
compliant nature; little to no pressure is transferred between
interfaces. Laird’s dispensing product portfolio includes both one
and two-part materials, as well as products specifically designed for
vertical stability and consistent dispensing.

High-Performance Products
(Tpcm
TM
and Tgrease
TM
)
High-performance products are used in applications where mechanical
tolerances and general design has been optimized for thermal
performance.
The Tpcm phase change product line is used in applications where
reliability, repeatability, and handling must be controlled to optimize the
performance as part of the total thermal solution. The Tpcm product line
is available in a screen printable formulation that offers the reliability
and performance of a phase change material with the low-cost handling
of thermal grease.
Tgrease is used in applications where a minimum bond line,constant
pressure, and ease of screen printing are desired for optimal
performance. Laird’s high-performance Tgrease products are
designed to maximize reliability by eliminating pump out in most
applications.
