Shin-Etsu Chemical Announces Development of a Low-Hardness, High-Thermally Conductive Silicone Soft Pad That Has Many Superior Properties

New Silicone Material Attains Excellent Cost-Performance
TOKYO--(Business Wire)--
Shin-Etsu Chemical Co., Ltd. (President: Chihiro Kanagawa; Head Office: Tokyo),
has developed and begun to market a low-hardness, high-thermally conductive
silicone soft pad, the "TC-CA Series," that offers excellent cost-performance.

The newly developed series of products have both high thermal conductivity and
excellent electrical insulation properties, which stem from Shin-Etsu`s advanced
polymer and thermally conductive filler composite material technologies.

In addition, compared to conventional products, the new silicone soft pad
product combines such superior properties as (1) high thermal conductivity, (2)
low-hardness that makes for good compressibility and a stress-relaxation
property that can reduce stress to heat modules (3) excellent workability and
processibility, and (4) low specific gravity.

The main application of this new series of silicone soft pad products will be
for countermeasures against the heat emanating from various electronics devices,
such as those mounted in notebook PCs, LED lighting, hybrid cars and electric
cars, and it meets the need for thinner and lighter weight device applications.

The TC-CA Series has a line-up of four kinds of products - the TC-CAS, TC-CAB,
TC-CAD, and TC-CAT. One can choose the most appropriate product depending on
your application or usage conditions. Commercial production is scheduled to
begin in December 2009.

These heat-dissipating thermal interface materials are thermally conductive
compounds fitted between the heat-generating unit, such as a computer`s CPU, and
the heat sink. Demand for thermally conductive silicone rubber sheet is
expanding for such heat-dissipation applications as in the growing number of
electronic components in automobiles and LEDs as well as in PCs, home
appliances, and electronic game units. Moreover, due to the increasing
miniaturization and higher performance of electronic devices, the need for more
effective heat-dissipation materials is further increasing.

Shin-Etsu Chemical has a line-up of various thermally conductive silicone
materials such as soft pad, insulating rubber, phase-change materials, two-sided
adhesive tapes, greases, gels and adhesive agents. Depending on the application,
it is possible to meet diverse heat-dissipation requirements, and Shin-Etsu will
go forward with product development to meet the future needs of a market that
will have even more sophisticated needs.

Silicones are highly functional materials that combine characteristics of both
organic and inorganic materials. They are materials that provide
high-value-added features for products in a wide range of industrial fields,
including electrical and electronic applications, automobiles, construction,
cosmetics and chemicals.
