Divinycell HCP - high performance PVC for subsea applications Divinycell HCP, a unique PVC formulation, is used from sea level to 700 meters depth and has an excellent track record in subsea applications for over 50 years. This grade meets the demand for a high performance, low density buoyancy material with excellent characteristics. It is widely used in submarines, subsea buoyancy units, ROVs, diving bells and impact protection structures. As a result of its excellent hydraulic compressive properties and closed cell structure, it has very low buoyancy loss and water absorption under long-term loading conditions. HCP stands for Hydraulic Crush Point and is defined as the point of pressure in Bar, where the material when subjected to an increasing pressure of 1-2 Bar/sec has lost 5% of its initial volume. The design of subsea buoyancy applications is complex, and consideration must be given to the buoyancy loss and uplift requirements over the expected lifetime and service conditions, with respect to long and short term hydraulic compressive creep, water absorption and hydraulic fatigue. Divinycell HCP at a glance - Excellent buoyancy performance - High resistance to creep - High impact resistance/damage tolerance - Excellent thermal properties - Thermoformable - Good insulation properties - Fast and easy to machine - Compatible with most common glues and resin systems
