Divinycell HCP grade has been developed to meet the demand for a high-performance, lightweight buoyance material with excellent characteristics. It is widely used in pipelines, floatation units, 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.

Divinycell HCP is recognised as the most cost efficient homogeneous foam buoyancy material for depths ranging from sea level to 2,300 ft. (700 meters). It is a partially cross-linked structural cellular material which is expanded using a CFC-free process.

HCP stands for Hydraulic Crush Point indicating the most important feature of this class of materials. HCP 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 has to be given to the required buoyancy loss and updrift over the expected lifetime and service conditions, with respect to long and short term hydraulic compressive creep, water absorption and hydraulic fatigue. Please contact DIAB for a design proposal.

Standard & Special Finishing

Divinycell HCP core can be supplied with a wide range of finishes to facilitate installation, enhance component quality and to meet specific process requirements.

Ready-Made Kits

For those involved in series production, Divinycell HCP can be supplied in ready-made construction kits where each piece is pre-cut, shaped as necessary and numbered to fit exactly into its designated place in the mold. This substantially reduces build times, saves labor costs, improves quality and cuts waste.
