Ultramid® is BASF's trade name for its line of polyamide (PA) products. BASF started manufacturing Ultramid® polyamides over 50 years ago. 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.
The Ultramid® extrusion grades, available in a wide variety of viscosities and additive packages, are used in nearly all fields of packaging. Ultramid® can also be used for the production of stretched monofilaments such as industrial wires, fishing lines, tennis racket strings, weed trimmer lines and bristles.
