Trelleborg manufactures a range of high performance, low density syntactic foam for deep sea buoyancy applications called Eccofloat®. These composite foams provide ultra-low densities by selecting only the highest specification hollow glass microspheres, called Eccospheres®, and combining them within a rigid, high strength resin system. The syntactic foam is typically cast into standard blocks.
Oceanographers also depend on syntactic foams to suspend instrumentation in deep ocean studies. For these applications, the syntactic foam is used in either block form or custom molded shapes for installation in manned and unmanned submersibles such as the legendary Alvin and Jason vehicles that were used to discover and explore the Titanic.
Trelleborg produces various grades of syntactic foams to meet a broad range of requirements.
EL Grade epoxy syntactic foams have been the materials of choice for manufacturing manned and unmanned submersibles for years with their range of densities and ability to withstand exposure to diesel fuels and hydraulic fluids.
TG Grade syntactic foams are lightweight and economical for building manned and remote operating vehicles. The foams have also been used to manufacture mine neutralization systems because of their zero magnetic and sea water comparable acoustic signatures and to fabricate eyebrows for submarines because of their buoyancy, acoustic profile and ability to significantly improve sonar functions.
DS Grade syntactic foams combine lightweight glass Microballoons with multi-functional epoxy resin to produce ultra-high strength-to-weight materials for high-performance, deep sea applications including unmanned and manned submersibles.
SG Grade syntactic foams offer a more economical solution which is also castable. It is available at all depths and is suitable for all subsea equipment.
