Title:
POLYCARBONATE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2018159004
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition improved in light reflection characteristics, dimensional stability and thermal stability.SOLUTION: A polycarbonate resin composition contains, based on 100 pts.wt. of a resin component comprising (A) 10-100 wt.% of a polycarbonate-polydiorganosiloxane copolymer resin (component A) and (B) 0-90 wt.% of an aromatic polycarbonate resin (component B), (C) 10-40 pts.wt. of a titanium dioxide pigment (component C), (D) 10-40 pts.wt. of at least one inorganic filler (component D) selected from the group consisting of an acicular inorganic filler, a fibrous inorganic filler and a tabular inorganic filler, and (E) 0.01-1 pt.wt. of a phosphate-based stabilizer (component E). The polycarbonate resin composition has a linear expansion coefficient in a parallel direction at 23-55°C of 0.5×10/°C or less.SELECTED DRAWING: None
