BASF is introducing an additional member of the new Ultramid® Endure line of plastics. With a glass fiber content of 50 percent, Ultramid Endure D3G10 offers considerably improved stiffness at elevated temperatures.

The first member of the new highly heat aging-resistant polyamide family, Ultramid Endure D3G7 with a glass fiber content of 35 percent, which was introduced in the year 2010, has already found a great deal of interest and will be found in serial application at several processors soon. Now, the company is offering, for the requirements of intercooler end caps in particular, the grade with 50 % glass fibers. With a tensile modulus of more than 17,000 MPa after aging (measured in accordance with ISO 527-2/1993), the new material is almost 50 percent stiffer than the D3G7 version.



As the first grade, Ultramid Endure D3G10 is resistant to heat aging up to 220 °C and suitable for parts in the charge air system. This will allow even more metal than previously to be replaced in the engine compartment. Compared to high-priced specialty polyamides use of Ultramid Endure results in a significant system cost reduction.
