Launch of PPA compounds / Suitable for automotive parts
BASF (Ludwigshafen / Germany; has introduced a new range of polyphthalamide (PPA) compounds based on PA 6T/6I with enhanced strength and stiffness.

The "Advanced T1000" group has the highest strength and stiffness of the “Ultramid” family and can withstand a broad temperature range from -40°C to above 80°C (conditioned) and up to 120°C (dry). The compounds have a partially aromatic chemical structure that BASF said offers high resistance to humidity and aggressive media, such as hot coolants and oils, outperforming conventional PA products and many other PPA materials on the market.

The material is suitable for a wide range of products that have to withstand tough conditions in various industries, including automotive where manufacturers are increasingly seeking new materials for replacing metal. “The demands on the materials have increased drastically in recent years, mostly because of trends such as ongoing miniaturisation, higher efficiency targets and functional integration,” said Abdullah Shaikh, head of BASF’s global PPA team. Applications include thermostat housings and water pumps, fuel circuits, actuators and clutch parts, coffee machines, water distributors and heating systems, among others.

The initial portfolio comprises a range of heat-stabilised GRP standard grades, glass fibre-reinforced grades with improved hydrolysis resistance and a long glass fibre-reinforced, highly heat-stabilised compound for outstanding mechanical performance, especially at higher temperatures. Grades with different heat stabilisers are also available, depending on individual application requirements.

Advanced T1000 materials are suitable for injection moulding. BASF said there are different possibilities for post-processing such as laser marking or welding with Advanced T1000 grades, and other PA or PPA compounds.
