ABSTRACT:
Sealing materials for longitudinal sealing of electrical and optical communication cables and cable connectors are comprised of a mixture of a polyol, a diisocyanate, a polymerization catalyst and a plasticizing component, such as a monofunctional aliphatic alcohol. Exemplary polyols are selected from the group consisting of a polyester-polyether-polyol or a polyester-polyol. An exemplary diisocyanate are selected from the group of hexamethylene-1, 6-diisocyanate and trimethyl hexamethylene diisocyanate and an exemplary plasticizing component is 2-octyldodecanol. Such sealing material can be provided within the interior of communication cables about the various elements thereof and/or within cable connectors or sleeves wherein individual elements of two or more communication cables are joined.
