Eccofloat®

Eccofloat® are a range of high performance, low-density syntactic foams designed for deep sea buoyancy applications. These composite foams provide ultra-low densities by selecting only the highest specification hollow glass microspheres 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.

The Making of the Deep Submergence Vehicle (DSV) Limiting Factor - A Documentary by Nick Verola

This film details the design and construction of the first commercially-certified submersible capable of repeated dives to the very bottom of the ocean -- Challenger Deep. The film takes you behind the scenes to understand the difficulties in designing and building it, and the international team that made it happen.

Eccofloat® DS

Eccofloat® DS range of 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.

Eccofloat® EL

Eccofloat® EL range of 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.

Eccofloat® DG

Eccofloat® DG range of syntactic foams have been developed for less density critical applications. Eccofloat® DG has excellent mechanical properties for structural applications.

Eccofloat® TG

Eccofloat® TG range of syntactic foams are lightweight for building manned and remote operating vehicles. The foams have zero magnetic and seawater comparable acoustic signatures making them ideally suited to applications which include mine neutralization systems, Sonar Domes, and Acoustic Windows.
