Document Type and Number:

WIPO Patent Application WO/2007/052727

Kind Code:

A1

Abstract:

Disclosed is a polyarylene sulfide composition having excellent thermal conductivity, dimensional stability, heat resistance and low gas generation. This polyarylene sulfide composition is useful for electrical and/or electronic components or applications such as automobile electrical components. Specifically disclosed is a polyarylene sulfide composition containing a polyarylene sulfide (a), a metal silicon powder (b) and a fibrous filler (c). Preferably, this polyarylene sulfide composition further contains a mold release agent (d) and at least one thermal conductive filler (e) selected from the group consisting of a scale-like boron nitride powder (e1) having a hexagonal structure, a coated magnesium oxide powder (e2) which is coated with a double oxide of silicon and magnesium and/or a double oxide of aluminum and magnesium, a high-purity magnesite powder (e3) which is composed of a magnesite mainly containing magnesium carbonate and having a magnesium carbonate content of 98-99.999% by weight, and graphite (e4).
