A mineral oil-free cured cable splice encapsulant comprises between about 20% and about 60% polyurethane, by weight of the cured encapsulant, the balance comprising diluent(s) and/or plasticizers, and typically has a cure and typically has a cure time of at least 50 minutes at 25 DEG C. The relatively long cure time, together with other properties of the material, including a viscosity typically between 150 and 1500 centipose, and relatively good "bonding" to plastic-insulated conductors, results in improved water-intrusion resistance of splices enveloped in the novel encapsulant. |
