Corecell™ A-Foam - Gurit - #1

Text version of the page

Gurit Corecell™ A-Foam Structural Core Material Exceptional impact tolérance Suitable for dynamically-loaded structures Superior styrene and temperature resistance to linear PVC foam Highly thermoformable Ideal for resin infusion Introduction Corecell A-Foam shares the benefits of SAN chemistry common to all Corecell products. Built in toughness - Very high ductility and damage tolerance Environmental stability - High tolerance for heat and chemical exposure Fine cell size - Resin absorbtion is very low, saving both weight and cost Superior uniformity - Low density variation Compatibility - Suitable for use with all polyester, vinylester and epoxy resins Handling - Tough and easy to machine No inhibition - Corecell does not inhibit epoxy curing mechanisms Corecell A-Foam is the original Corecell material, developed because of frustrations with inadequate PVC core technology in marine sandwich structures. Corecell A-Foam is well known for it's incredible toughness and resistance to cracking, which comes from its high ductility. Corecell A-Foam can elongate up to 65% in shear before failure, making core shear failure in a laminate almost impossible. Tests and experience show that Corecell A-Foam is the most reliable core material for dynamic loading situations where PVC and balsa may fail due to poor shear elongation properties. This reliability has made Corecell A-Foam the preferred choice amongst offshore yachtsmen for twenty years. For the manufacturer, Corecell A-Foam offers the benefit of high resistance to styrene and other chemicals and better thermal stability than linear-PVC foam. Corecell A-Foam is also highly thermoformable, which is useful in many applications where cutting the core material is undesirable. Corecell A-Foam is available in every resin infusion format and is compatible with polyester, vinylester and epoxy resin systems. The low resin absorption characteristics of Corecell and it's unique knife-cut formats deliver higher performing infusions, low resin cost and low weight. Gurit's global technical team have 10 years experience in resin infusion and offer on-site support for Corecell customers. This combination makes Corecell a key part of a reliable package.
