Diab's closed cell PVC foams offer high buoyancy per weight, low density, and high uplift, used in ROVs, AUVs, submarines, diving bells, and offshore renewable energy solutions. Shallow water buoyancy benefits from low-density foam which chemical reistant, handles high impact, and offers longterm creep resistance. For depths below 700 meters, Diab / SGS provides built to print solutions in Syntactic foam.
