The object of the present invention is to provide a polyarylene sulfide composition having excellent thermal conductivity, dimensional stability, heat resistance and low gas property, which is particularly useful to applications of electric parts such as electric and/or electronic parts or automobile electric parts. The present invention relates to a polyarylene sulfide composition comprising a polyarylene sulfide (a), a metal silicon powder (b), a fibrous filler (c), and preferably a release agent (d) and at least one thermally 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) coated with a complex oxide of silicon and magnesium and/or a complex oxide of aluminum and magnesium, a high purity magnesite powder (e3) which is a magnesite comprising magnesium carbonate as a main component and has a magnesium carbonate content of from 98 to 99.999% by weight, and graphite (e4).

Polyarylene sulfide composition

A flame retardant comprising (A) ethylenediamine-containing zinc phosphate and (B) a metal compound.

Flame retardant and flame retardant resin composition containing it

Fire retardant tablet is provided which is produced by tableting a fire retardant mixture containing heat-expandable graphite (A), and a water-soluble fire retardant synergist (B) or one containing additionally water-insoluble fire-retardant synergist (C). A method for fire retardation, a fire-retardant polymer composition, and a molded article of a fire-retardant resin by use of the fire retardant tablet are also provided. In the production of a fire retarding polymer composition containing heat-expandable graphite, the crushing of the heat-expandable graphite under melt-shearing is minimized.

Fire-retardant tablet, and fire-retarding method, fire-retardant polymer

Polyvinyl chloride based resin compositions improved in the vibrational energy absorbing ability are disclosed. The compositions comprises a specific class of phthalic acid esters and a specific class of phosphori acid esters. Articles formed of the compositions are also disclosed.
