Description
GNM1029 is a new type of physical foaming dielectric raw material, specialized for communication cable diameters from 0.8 to 22 mm. High expansion degree and good electrical properties are its main characteristics.
GNM1029 does not contain a nucleating agent so that a small amount has to be added during the extrusion process.
