Development Trend of Flame Retardant Shanghai Nylon Materials

Polyester has a wide range of uses due to its good physical properties, electrical properties, temperature resistance, ductility, wear resistance, wear resistance, self-lubrication, chemical resistance and other properties. The flame retardant Shanghai nylon material also promotes the change of flame retardant nylon due to its good flame retardant properties, excellent physical properties of mechanical equipment, remarkable electrical insulation properties, good high temperature reliability, new product development coordination ability and cost controllability. It becomes a high-quality material suitable for the vast majority of industrial production power installation projects, electronic equipment and household appliances.
