Extrusion Moulding Of “CAPLON” NYLON-6

Nylon-6 of higher R.V. 3.0-3.5 is suitable for extrusion moulding of rods, monofilament, profiles, tubing & many more applications. For extrusion moulding generally a temperature of 30-40 degree Celsius above melting point is maintained. Care should be taken to control moisture of Nylon-6(CAPLON) below 0.1 %( 1000 PPM). If more moisture is present while moulding, then extruded parts may contain bubbles & result in degradation of mechanical properties. Residual monomer content also should be as low as possible to maintain desired melt viscosity. The residual time inside the extruder must be maintained and die without any dead space should be used. Cylinder & die temperature should be maintained as given below:
