HEAT FUSIBLE OIL GELS |
摘要 |
The present invention is directed to a composition for a gel useful in fiber optic cable which has the normal consistency of a grease but which, if desired, will become a rubbery coherent gel upon heating; a method of making the heat-fusible gel, and a method of making a spliceable fiber optic cable, and a fiber optic cable. In the broadest sense, a heat-fusible oil gel composition for fiber optic cable is disclosed, comprising: from 50 to 80 wt. % of a grease-like gel based on a hydrocarbon oil containing from 2 to 10 wt. % of an S-EB or S-EP diblock polymer, or a mixture of these diblock copolymers, and from 20 to 50 wt. % of a grease-like gel based on a polar oil containing from 5 to 25 wt. % of an S-EB-S or S-EP-S triblock copolymer, or a mixture of these triblock copolymers. |

1. A heat fusible oil gel composition comprising:
a) from 50 to 80 wt. % of a gel based on a hydrocarbon oil containing from 2 to 10 wt. % of an S-EB or S-EP diblock copolymer, or a mixture thereof, and b) from 20 to 50 wt. % of a gel based on a polar oil containing from 5 to 25 wt. % of an S-EB-S or S-EP-S triblock copolymer, or a mixture thereof, where S, EB, and EP represent blocks of polystyrene, hydrogenated polybutadiene and hydrogenated polyisoprene, respectively. |
