POLYETHYLENIC RESIN RAW MATERIAL FOR WATER CROSSLINKING, POLYETHYLENIC RESIN COMPOSITION FOR WATER CROSSLINKING AND WATER-CROSSLINKED POLYETHYLENIC RESIN MOLDED PRODUCT USING THE SAME
POLYETHYLENIC RESIN RAW MATERIAL FOR WATER CROSSLINKING, POLYETHYLENIC RESIN COMPOSITION FOR WATER CROSSLINKING AND WATER-CROSSLINKED POLYETHYLENIC RESIN MOLDED PRODUCT USING THE SAME
PROBLEM TO BE SOLVED: To suppress oxidation deteriorating properties, to improve the thermal aging resistance and preservability and to improve further storage handleability in a polyethylenic resin raw material for water crosslinking.;SOLUTION: The polyethylenic resin raw material for water crosslinking is obtained by using 100-50 mass% of a linear low-density polyethylene resin granule satisfying the following properties (a) to (c) and having 0.2-1.5 mm average grain diameter and 0-50 mass% of a granule or a pellet of another polyolefin resin. (a) 0.91-0.94 g/cm3 density, (b) 0.1-5 g/10 min MFR (melt mass flow rate) and (c) ≥30 min OIT (oxidation induction time) at 150°C.;COPYRIGHT: (C)2006,JPO&NCIPI
