Gurit® Corecell S - Structural Foam Core (v9) - 1

Corecell™ S-Foam Structural Foam Core n High hydrostatic crush strength and water resistance n Outstanding mechanical properties n Ultra-fine cell size n Lower density than resin-based syntactics Introduction Corecell S-Foam shares the benefits of SAN chemistry common to all Corecell products. Built in toughness – High ductility and damage tolerance Fine cell size – Resin absorbtion is very low, saving both weight and cost Superior uniformity – More consistent density than resin-based syntactics Eliminating outgassing – Corecell eliminates the problems of foam outgassing Compatibility – Suitable for use with all polyester, vinylester and epoxy resins No inhibition - Corecell does not inhibit any epoxy resin curing mechanisms Handling – Robust for easy machining and use Corecell S-Foam 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, Corecell S-Foam 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 Corecell products, Corecell S-Foam 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 Corecell S-Foam. Complex shapes can be created in Corecell S-Foam using a variety of milling, routing, sawing and drilling techniques. Corecell S-Foam is available at lower densities that can be achieved with a syntactic, with standard products ranging from 200 to just over 300kg/m3. PDS-Corecell S-Foam-8-0211 1
