Gurit® Corecell™ S has been designed specifically for use in sub-sea buoyancy applications. Its resistance to crushing means that it can withstand depths of over 900m, and its closed-cell structure gives it a high water resistance that ensures buoyancy is maintained over time. With its very high compressive strength, Gurit® Corecell™ S can also replace other materials, such as plywood, when creating high strength inserts for through-bolting in composite laminates. Having the smallest cell size of all the Gurit® Corecell™ products, Gurit® Corecell™ S absorbs very little resin in lamination processes, thus minimising weight gain. The small cell size and the product’s inherent toughness also contribute to the excellent machineability of Gurit® Corecell™ S. Complex shapes can be created in Gurit® Corecell™ S using a variety of milling, routing, sawing and drilling techniques. Gurit® Corecell™ S is available at lower densities that can be achieved with a syntactic, with standard products ranging from 200 to just over 300kg/m3.
