Zusammenfassung:A thixotropic gel composition is disclosed as a fiber optic buffer tube compound. The composition as a fiber optic buffer tube compound is resistant to syneresis and phase separation, and to ingress of water and water vapor. The composition has low temperature flowability at -40 DEG C. as determined by a cone penetration test and has continued high temperature consistency at +80 DEG C. The composition retains its low temperature flowability property after a heat aging test at 93 DEG C. The composition comprises polybutene, polyethylene wax, hydrophobic fumed silica, and, optionally, an antioxidant.
