Residency Buoyancy

Residency Buoyancy

Trelleborg manufactures a range of ultra-high performance, low density syntactic foams, specifically for RROV and RAUV residency vehicle buoyancy applications. These composite foams provide very low densities by incorporating the highest specification hollow glass microspheres and combining with a rigid, high strength resin system.

Engineered to withstand long term immersion, our residency buoyancy solutions can withstand the constant hydrostatic conditions created by the challenge of residency applications. The unique polymer syntactic matrix provides superior resistance to compression ensuring consistent performance and stability.

Manufactured by Trelleborg Applied Technologies in the UK, our in-house R&D team can engineer solutions to meet your individual project requirements.
