II. P E compound, based on PE resin, isproduced and pelletized with the double corrugated screw, in which variousadditives are added. The compound is according to GB 15065-94 and IEC 60502. The compound has outstandingperformances of processing, physical, mechanical and electrical properties.

III. Processing: It is recommended thatcompound 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 notexceed 100℃.

Thefollowing temperature(℃) profile of extruder is recommended:

Type	Zone 1	Zone 2	Zone 3	Zone 4	head	die
NDH	180	190	200	210	220	230
LDH	170	180	190	200	210	220
MH	180	210	220	230	245	240
GH、NGJ	190	215	230	245	245	240
NLDJ	160	180	195	200	200	210
ZPE	140	150	160	170	170	165
RDH	140	160	175	180	190	190

Note: The processing parameters are forreference only, optimal conditions may vary according to the equipment used.The cooling water tank should be used sectionally cooling with warm-waterechelon in order to reduce internal stress.
