Temperature Range C | 160- 180 | 180-200 | 200-220 | 220-230 |
- Above temperature is only for reference.
For general cable insulation layer (1 mm in thickness) can be cross-linked after bathed in 90C above hot water for 4 hours. If the thickness of insulation is larger, it should be appropriate to extend the bath time. Extended by 1mm/4h or extend the time according to the specific heat for extended data.
Keep at room temperature; Storage environment should be clean, dry and ventilated; Best use within six
months from the date of production; Please use up in 16 hours after bag is opened.
Packing: 25kg/bag (moisture-resistant aluminum laminated bags + composite paper bags).
Storage: Store in clean, dry, ventilated environments at room temperature. Use within 6 months of production; consume within 16 hours after opening.
