BASF’s Ultramid® grades are molding compounds on the basis of PA6, PA66 and various co-polyamides such as PA66/6. The range also includes PA610 and semi-aromatic polyamides such as PA6T/6, PA6T/66, PA6T/6I and PA9T.
The molding compounds are available unreinforced, reinforced with glass fibers or minerals and also reinforced with long-glass fibers for special applications. Ultramid® is noted for its high mechanical strength, stiffness and thermal stability. In addition, Ultramid® offers good toughness at low temperatures, favorable sliding friction behavior and can be processed without any problems.
The most important properties of Ultramid®:
Ultramid® ‒ versatility in material and application
Because of the manifold and tailor-made characteristics of Ultramid® many applications are possible, especially in automotive construction, electrical engineering and electronics, in household technology, industrial connection, photovoltaics, in construction and installation, furniture, the sanitary industry and in mechanical engineering.
Properties of Ultramid® (PA)
Ultramid® is the trade name for polyamides supplied by BASF for injection molding and extrusion. The product range includes PA6 grades (Ultramid® B), PA66 grades (Ultramid® A), special polyamides like PA610 (Ultramid® S Balance), polyphthalamides such as PA6T/6I (Ultramid® Advanced T1000), PA6T/66 (Ultramid® Advanced T2000), PA9T (Ultramid® Advanced N) or PA6T/6 (Ultramid® TKR), as well as special grades based on copolyamides. Ultramid® A is produced by condensation polymerization of hexamethylene diamine and adipic acid, Ultramid® B by hydrolytic polymerization of caprolactam. These materials are obtained from petrochemical feedstocks such as benzene, cyclohexane and p-xylene. Ultramid® is noted for its high mechanical strength, stiffness and thermal stability.
Processing of Ultramid®
Ultramid® can be processed by all methods known for thermoplastics. The main methods are injection molding and extrusion. Complex moldings are economically manufactured in large numbers from Ultramid® by injection molding. The extrusion method is used to produce films, semi-finished products, pipes, profiled parts, sheet and monofilaments. Semi-finished products are usually further processed by cutting tools to form finished molded parts.
Specific Ultramid® Grades
The product range of Ultramid® also comprises grades for special applications.
