ABSTRACT:
This invention is directed to a rheologically modified composition containing scleroglucan in an polyol base fluid. The amount of scleroglucan present in the composition is an effective amount to viscosity an polyol base fluid to the point of substantially reducing convection flow in the composition. The composition may be used as an effective thermal insulation material. Applications for this type of insulating material include, among others, use as a de-icing fluid and use as a pipeline insulator. The rheologically modified insulation composition of this invention may be particularly suitable for maintaining high oil temperature during conveyance within a pipe located in a relatively low temperature environment such as sea water.
