Solvay Advanced Polymers

Solvay Advanced Polymers Llc : 12 September, 2006  (Company News)
The challenge was to find a plastic that would quietly and steadily house a cooling fan for high-end servers used 24 hours-a-day, seven days-a-week at temperatures two-to-three times normal room ambient levels.
The challenge was to find a plastic that would quietly and steadily house a cooling fan for high-end servers used 24 hours-a-day, seven days-a-week at temperatures two-to-three times normal room ambient levels.

After 18 months of product testing, Nidec America Corporation, a world leader in
cooling fan technologies, selected Solvay Advanced Polymers, L.L.C.ís AMODEL
Polyphthalamide over two competing products.

ďAny of the candidate materials we tested for the six-inch square fan housing would have worked if we only considered room temperature operation,Ē said John W. Hoover, director of engineering for Nidec.

However, he said cooling fans in high-end servers must be capable of operating 24/7 at rotational speeds of 5,000 revolutions per minute in continuous temperatures in the range of 140-160 degrees Fahrenheit (60-70 degrees Celsius).

The AMODEL material used by Nidec for its new, spacing-saving TA600DC fan
housing is a 33 percent glass-reinforced grade of PPA resin with a UL-94 V-O flammability rating. It was developed specifically for connector applications that require compatibility with both infrared and vapor phase soldering operations typically used in the electronics industry, as well as for other flame resistant applications requiring excellent electrical and high temperature performance.
The resin processes readily using conventional injection molding equipment and
methods. It offers high flow and short molding cycles. The processing window is relatively broad, and mold temperatures as low as 150 degrees Fahrenheit (65 degrees Celsius) can be used.
