Embodiment approach 1

[0086] Embodiment 1: A composition, based on the total weight of polymer and filler, comprising: 0.5 to 91 weight percent of a poly(phenylene ether) and poly(phenylene ether)-polysiloxane intercalated Poly(phenylene ether)-polysiloxane block copolymer reaction product of segment copolymer, 1 to 50 weight percent homopolystyrene; 3 to 25 weight percent comprising organophosphate, phosphazene, or combinations thereof flame retardant; and 5 to 40 weight percent reinforcing filler.

Embodiment approach 2

[0087] Embodiment 2: The composition of Embodiment 1, further comprising 5 to 90.5 weight percent of a second poly(phenylene ether).

Embodiment approach 3

[0088] Embodiment 3: the composition of Embodiment 1, comprising 2 to 20 weight percent of the poly(phenylene ether)-polysiloxane block copolymer reaction product and 10 to 60 weight percent of the second poly(phenylene ether).

Abstract

A composition includes specific amounts of a poly(phenylene ether), a poly(phenylene ether)-polysiloxane block copolymer, a homopolystyrene, a flame retardant, and a reinforcing filler. The composition exhibits a desirable balance of flame retardancy, heat resistance, stiffness, and melt flow. Articles that can be prepared from the composition include frames and chassis of office equipment, fusermodule parts for printers, copiers, and facsimile machines, cooling fan blades, cooling fan housings, parts for automotive kinetic energy recovery systems, and parts for electric vehicle junction boxes.

Description

Background technique [0001] Poly(phenylene ether) is a plastic known for its excellent water resistance, dimensional stability and inherent flame retardancy. Properties such as strength, stiffness, chemical resistance, and heat resistance can be tailored by blending it with various other plastics to suit a variety of consumer and industrial products such as sanitary ware, electrical boxes, automotive parts and Insulation requirements for wires and cables. [0002] Some applications of poly(phenylene ether) based compositions require significant flame retardancy. Examples include moldings in the construction, transport, electronics and solar power industries. Poly(phenylene ether) is inherently flame retardant, but it is often blended with other components such as impact modifiers and flow promoters, which, while improving their processing and mechanical properties, also reduce the obtained Flame retardancy of the composition. Therefore, blends of poly(phenylene ether) with...
