Abstract
Official abstract text for this publication.
A peroxide crosslinked resin composition includes a base polymer (A) including 50 to 90% by mass of a first copolymer component (a1) including one of or a mixture of two or more first ethylene α-olefin copolymers having a density of 0.864 to 0.890 g/cm 3 , a melt flow rate (MFR) of 1 to 5 g/10 min, and a melting point of not higher than 90 degrees Celsius, and 10 to 50% by mass of a second copolymer component (a2) including one of or a mixture of two or more second ethylene α-olefin copolymers having a melt flow rate (MFR) of not smaller than 30 g/10 min, and a melting point of 55 to 80 degrees Celsius, an inorganic filler (B) added in a ratio of from 80 parts to 150 parts by mass with respect to 100 parts by mass of the base polymer (A), and a peroxide crosslinker (C).
First claim
Opening claim text (preview).
What is claimed is: 1. A peroxide crosslinked resin composition, including: a base polymer (A) including 50 to 90% by mass of a first copolymer component (a1) comprising one of or a mixture of two or more first ethylene α-olefin copolymers having a density of 0.864 to 0.890 g/cm 3 , a melt flow rate (MFR) of 1 to 5 g/10 min, and a melting point of not higher than 90 degrees Celsius, and 10 to 50% by mass of a second copolymer component (a2) comprising one of or a mixture of two or more second ethylene α-olefin copolymers having a melt flow rate (MFR) of not smaller than 30 g/10 min, and a melting point of 55 to 80 degrees Celsius; an inorganic filler (B) added in an amount of from 80 parts to 150 parts by mass with respect to 100 parts by mass of the base polymer (A); and a peroxide crosslinker (C). 2. The peroxide crosslinked resin composition according to claim 1 , wherein the inorganic filler (B) comprises a mean grain diameter of 0.8 to 2.5 μm. 3. An electric wire, comprising: a conductor; and an insulator formed around an outer periphery of the conductor by coating with the peroxide crosslinked resin composition according to claim 1 . 4. A cable, comprising: the electric wire according to claim 3 .
