POLYOLEFIN-BASED FLAME-RETARDANT RESIN COMPOSITION AND HEAT-RESISTANT, WEAR-RESISTANT AND FLAME-RETARDANT INSULATION ELECTRIC WIRE

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin-based flame-retardant resin composition having wear resistance and heat resistance, and to provide insulation electric wire improved in both wear resistance and heat resistance by using the same, and to provide automotive insulation electric wire with thin-walled coat in particular.;SOLUTION: The polyolefin-based flame-retardant resin composition has a tensile elongation at break of ≥150% at 200 mm/min strain rate and comprises 100 pts. mass of a base resin comprising 65-80 mass% of an EP random copolymer ≤10.0 g/10min(230°C, 2.16 kg) in MFR, 15-25 mass% of an acid-modified PP and 5-10 mass% of HSBR, 60-80 pts. mass of a silicone surface-treated magnesium hydroxide and 4-8 pts. mass of a phosphate salt-based flame retardant.;COPYRIGHT: (C)2006,JPO&NCIPI
