摘要： A communication cable includes a core comprising at least one transmission medium and a sheath system which is disposed about the core. Means are disposed within the cable for preventing the longitudinal migration of water through the cable core, said means including both a hydrophilic material and a hydrophobic material in cooperative communication with each other. Specifically, a hydrophilic, water-absorptive material is supported by a yarn which is helically wrapped about various sections of the communication core. In a copper cable, the water-absorptive yarn may be wrapped about individual twisted pair conductors or a unit consisting of a plurality of twisted pair conductors or the cable core itself. In addition to the helically-wrapped, water-absorptive yarn, the cable of the present invention includes a hydrophobic, water-blocking material interdisposed to fill all voids and interstices within the communication core.

摘要： An optical fiber cable (20) includes provisions in a core thereof for preventing the flow of water longitudinally along the core and for preventing freezing of such water. The provisions for preventing freezing of water within the core, which could effect adversely the optical fibers, includes an antifreeze material. Each of two tapes may be impregnated with an antifreeze material such as propylene glycol, for example, and used to provide a laminate with a superabsorbent powder therebetween. Advantageously, the cable may have suitable flame retardance so that it may extend from an outside manhole to distribution points within a building.

摘要： A cable of this invention includes a core comprising a plurality of coated optical fibers and a filling composition of matter which is disposed about the fibers. Typically, the fibers and the filling material are diposed within a tubular member which is disposed within a sheath system. The sheath system include longitudinally extending strength members and a plastic jacket. The filling composition which fills interstices in the core is one which includes an oil constituent which is a relatively high molecular weight aliphatic hydrocarbon. The aliphatic hydrocarbon is a synthetic oil such as polyalphaolefin or mineral oil. A relatively large percent by weight of an antioxidant system is used to prevent thermal oxidative degradation of the filling material as well as of materials in contact with the filling material. Advantageously, for stabilization and metal deactivation, the composition includes zinc dialkyldithiophosphate or diaryldithiophosphate. A styreneethylene propylene copolymer is also included in order to reduce oil separation of the filling material. A fumed silica is used to impart gel properties to the material.

摘要： A cable (20) includes a waterblocking member (29) which includes a superabsorbent polymer. The superabsorbent polymer includes an ionic constituent which is characterized in that its solubility product is substantially higher than that of carboxylate and in that it has a lower reaction rate for forming an anhydride than does carboxylate. The ionic constitutent may be selected from the group consisting of sulfate, sulfonate and phosphate and also includes a counter ion. Other constituents may include a carboxylate and a non-ionic group constituent. The superabsorbent polymer is such that the amount of crosslinking is sufficient to avoid the polymer going into solution, but is not so much as to affect adversely the water absorbency of the waterblocking member. Further, the superabsorbent polymer is much more salt tolerant and temperature tolerant than are prior art superabsorbent polymers.

摘要： The present invention generally is directed to compositions, products and methods that utilize superabsorbent polymers for flame-retarding. A preferred method includes improving flame-retarding characteristics in products by adding SAPs to the product. Prior to the step of adding the SAPs, the product exhibits a first limiting oxygen index and after the step of adding the SAPs, the product exhibits a second limiting oxygen index, with the second limiting oxygen index being higher than the first limiting oxygen index. Preferably, the SAPs can be pre-loaded with moisture, thereby potentially further increasing the flame-retarding characteristics of the product. In a preferred embodiment, the product is configured as a cable, with the outer jacket of the cable incorporating the SAPs.
