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 t
