A polyurethane-based cable splice encapsulant further comprises about 25-70% b.w. ester plasticizer, and, optionally, no more than 35% b.w. diluents, preferably less than 15% b.w. diluents, and has a cure time of at least 50 minutes at 25%. The relatively long cure time, together with other properties of the material, including a viscosity typically between 0.15 and 1.5 Pa.s (150 and 1500 centipoise), and relatively good "bonding" to plastic-insulated conductors, results in improved water-intrusion resistance of splices enveloped in the novel encapsulant. |
