2)excellent temperature resistance, high heat distortion temperature.
3)excellent mechanic and chemical property
7)high resistance to fuels, oil, fats and many solvents
Cylinder temperatures: 240-270 0c
Nozzle temperature: 260-270 0c
Mold temperature: 40-120 0c, suitable temperature 60-80 0c
Screw speed: 60-120 rpm, to be chosen in such a way that
plasticizing time is just within cooling time.
Pressure Injection pressure: 500-1200 kg/cm2
