Buoyancy Foam
Buoyancy Foam
Expanded Polystyrene is lightweight and environmentally friendly. EPS buoyancy systems contain no CFCs, HCFCs, or blowing agents. The material also has the added benefit of reduced noise compared to other drum flotation options.
Expanded polystyrene is non-biodegradable and offers no food value for bugs and animals.
