Product Description
GNM***9 is a new type of physical foaming dielectric raw
material, specialized for communication cable diameters from 0.8 to
*2 mm. High expansion degree and good electrical properties are its
main characteristics.
GNM***9 does not contain a nucleating agent so that a small
amount has to be added during the extrusion process.

The above table is for reference only, the actual processing
temperature should be based on the technical parameters of the
extruder,through the gentle adjustment and practical operation to
set.
In order to prevent the increase of the bubble hole in the
extruder, the melting section should maintain the appropriate
pressure, if the pressure is not enough, there will be large gaps
and holes. The selection of the screen, the die core and the die
sleeve are all the factors that influence the melt pressure.
