Diagrams Water content: 0.1%If drying becomes necessary, a dehumidifying or desiccant dryer operating at 65 degC (149 degF) is recommended.Drying time is 5:1 to 4.0:1 1.5-2.0:1In general, the ratio of die size to finished tube diameter is about 1.5-2.0:1.The mandrel (pin) size is determined the same way in relation to the inner tube diameter.5mm and below.For larger diameters, a differential pressure vacuumThe vacuum sizer entrance should be about 3-9% larger than the finished tube outer diameter. Selection will depend on melt viscosity and die swell of the extrudate.5mm (.37") O.D., open tank quenching with normal tap water is suggested.Depending upon line speed, quenching distance can var5 to 12 meters (24.6-39.4 feet).A short air gap (die to quench water) is recommended for both tubing and cable jacketing for best flexibility.DisclaimerCopyright M-Base .
