1. Applications and cable specifications of MDPE granule:
Jacket of optical cable, aerial cable and power cable.
2. Description of MDPE granule:
PE compound, based on PE resin, is produced and pelletized with the double corrugated screw, in which various additives are added. The compound is according to GB 15065-94 and IEC 60502. The compound has outstanding performances of processing, physical, mechanical and electrical properties.
3. Processing of MDPE granule:
It is recommended that compound should be processed with extruder having a minimum L/D ratio of 25. Compound (not including ZPE) should be thoroughly dried before use, and the maximum drying temperature should not exceed 100°C.
The following temperature(°C) profile of extruder is recommended:
