For advanced metal replacement: bridging the gap between PA66 and PPA with Ultramid® T7000
For advanced metal replacement in structural parts, BASF is now offering a portfolio of polyamide (PA) and polyphthalamide (PPA) blends with better, more constant mechanical properties than PA66. Ultramid® T7000 outperforms PA66 regarding stiffness and strength in dry state and especially in presence of humidity. The polyphthalamide portion leads to a lower water absorption, which gives components an excellent dimensional stability. Ultramid® T7000 can be as easily injection-molded as PA66, giving parts a glossy and smooth surface finish. This unique combination of properties makes the PA/PPA blend a perfect metal replacement for structural parts which are exposed to moisture, e.g., automotive mirrors, air brake parts, valves but also furniture components.
