APPLICATION
RC HF 1012 is widely applied to the sheath of power cables, control cables, signal cables and other cables. Especially for the cable using at low temperatures.
PROCESSING
Normal extruding machine is applicable. It is recommended to use low compression ratio screw with length diameter ratio L/D 20 and compression ratio 1.2~1.5 to improve cable production efficiency. The recommended setting temperatures for each zone of the extrud er are as f o llows:
| Zone | Z1 | Z2 | Z3 | Z4 | Neck | Head |
