Publication number: 20130081850Abstract: A conduit that contains an elongate member that defines a hollow passageway is provided. The conduit may be used to convey electricity (e.g., jacket of a communication cable, raceway for protecting a communication cable, etc.), fluids (e.g., pipes), etc. In one embodiment, for example, the conduit may be a raceway for use in a plenum of a building structure. Regardless of the type of conduit, at least a portion of the elongate member is formed from a thermoplastic composition that contains a polyarylene sulfide and fire-resisting system. Due in part to the specific nature and concentration of these components, the present inventors have discovered that the resulting thermoplastic composition may have a relatively high melting temperature.Type: ApplicationFiled: September 4, 2012Publication date: April 4, 2013Applicant: TICONA LLCInventors: Christopher McGrady, Kaushik Chakrabarty, David McIlroy, Xinyu Zhao
