Product Texts
Partially aromatic polyphthalamide for injection molding and extrusion with strong mechanical properties especially at elevated temperatures and excellent chemical resistance for highly stressed parts, electrical insulating parts and cable ducts. The flame retardant is without halogens and can be characterized as polymer with extremely low water absorption and outstanding dimensional stability. It features a high melting point (300°C) and excellent melt stability.
