Polystyrene and polyurethane are widely used in the marine industry due to the buoyancy properties of both products.

Polystyrene is commonly used used as the core material in floating docks and pontoons. It is cost effective, has good floatation properties, and is easy to cut into custom pontoon profiles. Polystyrene can be used for both concrete and vinyl encasing of pontoons.

Polystyrene and polyurethane are used as buoyancy by boat builders. AU&S can supply both styrene and urethane cut to size, to fill the exact specifications of your design. Polyurethane is resistant to solvent attack making it the product of choice for surveyed craft.

Flotation baffles are used when containing spills on the water. AU&S supplies polystyrene and polyurethane for use as cores in baffles. We cut regular baffles (circular and rectangular) as well as custom shapes to fit the sleeve.

Polystyrene and polyurethane are great insulators and are widely used as the insulation in freezer or coolers in the marine industry.
