Abstract: A high temperature resistant glass fiber composition consists essentially of glass fibers having a nominal softening point of about 1000° F. (about 538° C.) which is capable of passing the British Standard 476 Part 4 fire test for building materials. The BS476-4 test begins at 750° C., substantially above the nominal softening point of the glass fibers. The increased temperature resistance is provided by coating the glass fibers with a halogenated resin latex binder and a calcium carbonate material. The method of making the glass fiber composition comprises depositing the resin latex and a calcium carbonate material on the glass fibers using a cationic flocculant. The preferred halogenated resin latex binder is selected from polyvinyl chloride and polyvinylidene chloride.

Abstract: A filler rod for occupying space in a stranded optical fiber communications cable having at least one buffer tube containing at least one optical fiber is disclosed. The filler rod comprises an elongated rod extruded from a polypropylene homopolymer, a polypropylene-polyethylene copolymer (i-PP) resin material, or preferably, from a polypropylene-polyethylene copolymer having a nucleating agent disbursed therein.
