LOW SPECIFIC GRAVITY THERMOPLASTIC COMPOUNDS FOR NEUTRAL BUOYANCY UNDERWATER ARTICLES

摘要

A thermoplastic compound is disclosed which has low specific gravity by virtue of the use of glass microspheres. Underwater articles, especially wire and cable, benefit from the insulative and buoyancy effect of using the thermoplastic compound with the other article components, engineered using buoyancy calculations to have consistent neutral buoyancy for reduced energy expenditure and convenient maneuverability of the underwater articles as if they were floating in outer space.
