Press Release Summary:
Ultramid A3W2G10 and Ultramid A3W2G6, 50% and 30% glass reinforced, respectively, perform in automotive engine applications and in turbo charging systems for hot side charge air cooler end cap and ducting. High heat-stabilized polyamide 66 grades handle continuous use in temperatures of 180-190Â°C and short term exposure up to 230Â°C. They feature optimized long-term heat aging characteristics and are resistant to engine fluids and cleaners.
Original Press Release:
New Ultramid® PA66 Grades from BASF - A Step Change in Hot Air Performance
Extending PA 66 into higher temperature applications
WYANDOTTE, MI, January 26, 2009 - BASF Engineering Plastics today introduced two new resins: Ultramid A3W2G10 and Ultramid A3W2G6. The label "W2" in the product nomenclature indicates that these are high heat-stabilized polyamide 66 grades for continuous use in temperatures of 180 C to 190 C and short term exposure up to 230 C. Typically, PA 66's long-term useful range is 140 C to 160 C.
Ultramid A3W2G10 and Ultramid A3W2G6, which are respectively 50 percent and 30 percent glass reinforced, are currently available and perform well in under-the-hood automotive applications, as well as in turbo charging systems for the hot side charge air cooler end cap and ducting. In many applications, these products can replace more expensive resins like polyphthalamide (PPA) and polyamide 46 as lower cost alternatives to meet customer cost reduction needs. These new grades also enable further metal-to-plastic replacement opportunities, thereby reducing vehicle weight, improving gas mileage and reducing emissions.
The first commercial adoption was in the end caps of charge air intercoolers manufactured by the Behr Company, where the requirements were 190 C continuous temperature and pressure fluctuating between 0.1 and 1.5 bar. This cooler is used on the Transit Connect/Tourneo Connect with a 1.8-liter TDCi common-rail turbo diesel engine.
