Abstract
The invention is an insulation material comprising a novolac cured polysulfide polymer resin. The material is used as a thermal insulator for subsea gas and oil production equipment, such as pipes and wellhead equipment. In order to decrease the maximum exothermic temperature generated by the resin during curing, hollow glass beads are added to the resin. The amine content of the hardener in a standard resin was adjusted to further decrease the maximum exothermic temperature. A fumed silica thixotropic material was also added to increase the viscosity of the mixture. These modifications allow the material to be cast in thick sections without cracking, leaking, or excessive expansion during curing.
