摘要:
A cable which may be used in buildings in concealed areas such as in plenums or in riser shafts includes a core (22) which includes at least one transmission medium each of which is enclosed with a non-halogenated plastic composition of matter. The core is enclosed with a jacket (28) which also is made of a non-halogenated plastic composition. The non-halogenated plastic material of the insulation includes a polyetherimide constituent and an additive system. The additive system includes an antioxidant/thermal stabilizer and a synergistic metal deactivator and may include a lubricant. For the jacket, the plastic material is a composition which may include a siloxane/polyimide copolymer constituent blended with a polyetherimide constituent and an additive system to improve processing and long term aging, or a siloxane/polyimide copolymer constituent with a flame retardant system.
