Product Description
Ultramid C40 L is a lubricated high viscosity, copolymer PA6/66 grade for the production of monofilaments and blown film. Its well suited for the production of high transparency, nonsymetric blown film with reduced curl. Its very low melting point compared to standard PA6 is advantageous for coextrusion with temperature sensitive polymers like EVOH.
