Structural Core Materials
GURIT® CORECELL™ A
STRUCTURAL CORE MATERIAL
- Ultra tough foam suited for slamming applications
- Exceptional impact tolerance
- Suitable for dynamically-loaded structures
- Superior styrene and temperature resistance to linear PVC
- Highly thermoformable
- Ideal for resin infusion
Gurit® Corecell™ A is the original Corecell material, developed because of frustrations with inadequate PVC core technology in marine sandwich structures. Gurit® Corecell™ A is well known for it’s incredible toughness and resistance to cracking, which comes from its high ductility. Gurit® Corecell™ A can elongate up to 65% in shear before failure, making core shear failure in a laminate almost impossible.
Tests and experience show that Gurit® Corecell™ A is the most reliable core material for dynamic loading situations where PVC and balsa may fail due to poor shear elongation properties.
For the manufacturer, Gurit® Corecell™ A offers the benefit of high resistance to styrene and other chemicals and better thermal stability than linear-PVC foam. Gurit® Corecell™ A is also highly thermoformable, which is useful in many applications where cutting the core material is undesirable.
Gurit® Corecell™ A is available in every resin infusion format and is compatible with polyester, vinylester and epoxy resin systems. The low resin absorption characteristics of Gurit® Corecell™ and it’s unique knife-cut formats deliver higher performing infusions, low resin cost and low weight. This combination makes Gurit® Corecell™ a key part of a reliable package.
