Melt extrusion temperatures in the range of 150ºC-200ºC are recommended, the specific temperature should be adjusted by actual operation condition.
Cross-linking condition and time of the hot set elongation to 100% (1 mm thick samples): vapor or water bath at 90ºC for 15min or at 80ºC for 30min,Natural condition (23ºC/50%/48h).
For excellent crossing-link, testing sample must be treated in vapor or hot bath (Minimum temperature:80ºC)
Storage and transport
Self-crosslinking Silane-XLPE Compound for wires and cables should be vacuum packed, the aluminum foil / polyethylene combination film bag for inner packing and PP woven bag / PE / Kraft paper bag for outer. A group and B group are packed in different bags: A group net weight(23.75±0.02)kg while B group(1.25±0.02)kg. Negative tolerance of each-ton material is unexpected. Besides, other packaging agreed on by both manufacturers and clients can be used.
Keep away from sunshine, rain and soaking during transport. Store in clean, dry, ventilated warehouse and the minimum storage temperature should be 0ºC.The product may be stored for up to 6 months . And it must be used out once within 8 hours after the inner packaging is opened.
