      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 PA6T/6 (Ultramid® T) and PA610 (Ultramid® S Balance) 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. In addition, Ultramid® offers good toughness at low temperatures, favorable sliding friction behavior and can be processed without any problems.

      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.

      The Ultramid® product range

      The basis of the Ultramid® grades are polyamides which are supplied in a variety of molecular weights or viscosities, have a range of additives and are reinforced with glass fibers or minerals. More detailed information on the individual products can be found in the Ultramid® product range.

      The Ultramid® range comprises the following groups of products:

    Ultramid® A

      (unreinforced) is the material with the greatest hardness, rigidity, abrasion resistance and thermostability. It is one of the preferred materials for parts subject to mechanical and thermal stresses in electrical, mechanical and automotive engineering.

    Ultramid® B

      (unreinforced) is a tough, hard material affording parts with good damping characteristics and high shock resistance even in dry state and at low temperatures. It is distinguished by particularly high impact resistance and ease of processing.

    Ultramid® C

      is the name given to copolyamides made from PA6 or PA66 monomers and further components. They exhibit different properties according to their composition.

    Ultramid® D

      are blends of PA6 and PA66 with other polyamides.

    Ultramid® S Balance

      is particularly resistant to chemicals and is also noted for its low moisture absorption. Ultramid® S Balance is preferably used in components that come into contact with media.

    Ultramid® T

      has a partially aromatic structure and is a highly rigid high-temperature polyamide (HTPA) with a high melting point, noted for its dimensional stability, high chemical resistance and constant mechanical properties across a wide range of different applications.

    Glass-fiber reinforced Ultramid®

      These materials are distinguished by high mechanical strength, hardness, rigidity, thermostability and resistance to hot lubricants and hot water. Parts made from them show dimensional stability and high creep strength. Glass-fiber reinforced Ultramid® T is moreover exceptional for its extra-ordinarily high heat resistance (up to 280°C). The portfolio is  supplemented by long glass-fiber reinforced Ultramid® Structure LFX grades.

    Reinforced and unreinforced grades with flame retardants

      Ultramid® grades with special additives including C3U, A3X2G5, A3X2G7, A3X2G10, A3U40G5, B3UG4, B3U30G6 and T KR 4365 G5 are particularly suitable for electrical parts required to meet enhanced specifications for fire safety and tracking current resistance.

    Mineral- and glass bead-filled Ultramid®

      The special advantages of these materials reinforced with minerals and glass beads lie in increased rigidity, good dimensional stability, low tendency to warp, optically appealing surfaces and good flow characteristics.


    Ultramid® Advanced N

      is characterized by very low water absorption, excellent chemical resistance and good mechanical properties at high temperatures in conditioned state.

    Ultramid® Advanced T1000

      has a very high, constant stiffness and strength over a temperature range of -40°C to over 80°C. It is resistant to high temperatures and against aggressive media.

    Ultramid® Advanced T2000

      is a polyphthalamide providing good E&E performance with a high melting point, low water absorption, good mechanical properties at high temperatures and good chemical resistance.

    Specific Ultramid® Grades

    The product range of Ultramid® also comprises grades for special applications.
