Structural Core Materials


  • Gurit® KerdynTM Green FR: up to 100% recycled PET based product range
  • Excellent FST performance (Evaluated against ISO11925-2 & EN13501-1; other certifications pending)
  • Withstands high process temperatures
  • Excellent chemical resistance
  • Good adhesion and mechanical properties
  • Recyclable

Gurit® Kerdyn™ Green FR have been developed to respond to the growing need for structural core materials with stable properties and improved resin uptake performance. Additionally the Gurit® Kerdyn™ Green FR allows to comply with the Marine, Civil and Transportation markets needs for material with good Fire, Smoke and Toxicity (FST) properties.

It offers a much lower cost FST material compared to high cost / high performance materials such as PMI (Rohacell), PEI (Ultem), PES (DIAB F) foams, addressing lower requirements and needs.

Starting with Gurit® Kerdyn™ Green extruded recycled structural PET core, flame retardant additives are added to improve FST properties. The manufacturing process remains the same as Gurit® Kerdyn™ Green, with slight variation in process settings.

Typical Applications

Gurit® Kerdyn™ Green FR can be processed at high temperatures, withstanding high exotherms and offers outstanding chemical resistance, good adhesion; as highly consistent extruded foam, it is ideal for wind energy, marine, industrial, and transportation applications.

Applicable processing techniques include vacuum infusion, bonding, prepreg, and thermoforming.
Available in a wide range of thicknesses.
