It is a copolyamide 6/66 grade of intermediate viscosity for the production of mulitlayer film and monofilaments. It is well suited for the production of nonsymetric blown film with reduced curl. Its lower melting point than standard PA6 is advantageous for coextrusion with temperature sensitive polymers like EVOH.
