Title:
RESIN COMPOSITION, RESIN COMPOSITION FOR OPTICAL PICKUP, AND MOLDED BODY FOR OPTICAL PICKUP
Document Type and Number:
WIPO Patent Application WO/2012/169279
Kind Code:
A1
Abstract:
Provided are: a resin composition which has excellent dimensional stability, moldability (in particular, thin-wall moldability), mechanical strength, adhesiveness and heat dissipation performance; a resin composition for optical pickup; and a molded body for optical pickup, which is obtained by molding the resin composition and is reduced in burr formation and optical axis shift, while having excellent weld strength. The resin composition is characterized by specifically containing 100 parts by mass of a resin composition that is composed of 60-96% by mass of (A) a liquid polymer and 40-4% by mass of (B) a polyarylene sulfide and 30-60 parts by mass of (C) graphite. The resin composition may contain 30-50 parts by mass of (D) a non-fibrous inorganic filler and 20-50 parts by mass of (E) a fibrous inorganic filler, if necessary.
