Balmoral SupathermPlus™
To eliminate problems associated with glass microsphere dissolution, Balmoral SupathermPlus utilises the same hydrolysis-resistant resin system as Balmoral Supatherm syntactic foam but simply omits the hollow glass microspheres. As well as being essentially immune to hydrostatic compression, this non-cellular resin system exhibits extremely low water ingress rates and saturation values.
As a result, whilst the start-of-life k-value of SupathermPlus is higher than that of a syntactic foam system, it suffers negligible deterioration at depth over its service life.
The particular advantage of the microsphere-free Balmoral SupathermPlus system is that its ultra-stable k-value is achieved and maintained at temperatures up to and beyond 110°C, temperatures at which all microsphere-containing systems – and the majority of pure polymer systems such as polyurethane and commodity epoxies – would have suffered massive water ingress, degradation and k-value increase.
Applications
The Balmoral Supatherm insulation systems are most commonly used in flooded, modular insulation systems for manifolds, ‘Christmas trees’, hybrid riser towers, flooded sealine bundles and connectors and flanges in insulated flowlines.
