DuPont Selar® PA 2072 Nylon Barrier Resin
Categories:	Polymer; Film; Thermoplastic; Nylon (Polyamide PA); Nylon, Barrier Film Copolymer
Material Notes:	Selar® PA 2072 is an amorphous nylon (polyamide) resin which is specially designed for blending with ethylene vinyl alcohol (EVOH) copolymers. Selar® PA 2072 can be tumble-blended with most grades of EVOH to form blends which combine the excellent barrier properties of EVOH with the deep-draw thermoforming properties, processing flexibility and moisture-insensitivity of Selar® PA. In addition, Selar® PA 2072 provides better adhesion in blends with EVOH than other grades of amorphous nylon, and this may allow converters to use less expensive adhesives.
