Deepwater Pure Syntactic Foam

A Wide Range of Densities From 1,000 to 12,000 msw

High-Performance Foams for Demanding Environments

ALSEAMAR offers a complete range of advanced technical foams, each designed to meet the specific challenges of subsea applications — from surface to ultra-deep depths.

Pure Syntactic Foam

Syntactic foam is composed of hollow glass microspheres embedded in a solid resin matrix. It offers extreme pressure resistance combined with the lightweight densities in the harshest environments.
