Polyurethane buoyancy foam is a machinable, hydrostatic, pressure-resistant polyurethane foam with a density typically between 30 and 100 kg/m³ that provides buoyancy underwater depths up to 1,200 feet, which plays an important role in the deep-sea environment. This article will analyze the polyurethane floating foam from three dimensions, such as characteristics and application test depth.
Main Featurtes of the Polyurethane Buoyancy Foam
• Easy to machine, coat and spray paint
• Superb compressive and insulation properties
• High impact resistance
• Biologically inert
• Compatible with many types of adhesives
• Normal operation temperature up to 230°F (110°C)
Available for Polyurethane Buoyancy Foam
• Underwater buoyancy
• Untethered underwater robotics (ROV/AUV)
• Semi-submersible craft
• Pipeline flotation
• Underwater pumps for offshore drilling rigs
• Subsea mooring buoyancy：oil tankers, production vessels, semi-submersible drilling platforms or deep-sea platforms
