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.
