Document Type and Number:
Japanese Patent JPWO2022163197
Kind Code:
A1
Abstract:
A resin composition contains: a base resin including a polyolefin; a modified polyolefin obtained by grafting a polar group onto a polyolefin; and an inorganic filler including magnesium oxide and surface-treated with a silane coupling agent. A remaining rate R of the inorganic filler in a fractured frozen surface is 50% or more. The remaining rate R is calculated using the following expression (1). R = (Df/Dc) ×100 . . . (1). Df represents a density of the inorganic filler remaining in a fractured surface of a sheet formed of the resin composition containing the base resin, the modified polyolefin, and the inorganic filler, when the sheet is immersed in liquid nitrogen for 1 hour and then fractured. Dc represents a reference density of the inorganic filler detected in a cut surface of the sheet formed of the resin composition, when the sheet is cut at 24°C using a focused ion beam without being frozen.
