Reference cross-linking conditions
For general cable insulation layer (1 mm in thickness) can be cross-linked after bathed in 90℃ 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.
Storage
- 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.
Product packing
- 25kg in moisture resistant aluminum laminated bags with composite paper bags outside;
- Palletized bottom.
