High-performance buoyancy foam and sandwich core solutions for submarines.
When pressure increases, performance must hold. Diab’s high strength and high buoyancy closed-cell foam cores provide outstanding resistance to compression and other forces, making them a natural choice for both buoyancy and structural sandwich applications in submarines. Our high-performance buoyancy foams offer long-term creep resistance, improved thermal and acoustic resistance and good dielectric properties.
From trim and ballast to auxiliary flotation units, our lightweight foams offer high uplift per weight and low creep over time, ensuring stable operation under demanding conditions. With decades of experience in defense and subsea systems, Diab is a trusted partner for reliable solutions beneath the surface.
For operations beyond 700 meters, all the way down to the seabed, we offer tailor-made buoyancy systems in syntactic foam through Subsea Composite Solutions, a dedicated division within Diab.
