Marine Subsea Group AS, supplies advanced Subsea Buoyancy and Ancillary products for use in mooring systems and petroleum production sites world wide
Syntactic foam is the core material enabling the manufacturing of buoyancy that can withstand the enormous hydrostatic pressure at thousands of meters of depth.
Syntactic foams are composite materials synthesized by filling a polymer matrix with hollow particles called microballoons. The presence of hollow particles results in lower density, higher strength, and a lower thermal expansion coefficient.
The compressive properties of syntactic foams primarily depend on the properties of the microballoons, whereas the tensile properties depend on the matrix material used in their structure.
Marine Subsea Group syntactic foams are in addition normally modified by the addition of larger diameter spheres. The resulting "composite" foams are less dense and less expensive than the "solid" foams.
Our syntactic foam solutions cover the needs for producing subsea buoyancy from subsurface down to several thousand meters depth.
