Core Materials

Sandwich core laminates can be used to stiffen various fiberglass applications such as boat hulls, storage tanks etc.

  • Balsa wood remains one of the most popular core materials in the industry, thanks to its moderate strength and affordability over PVC and honeycomb.
  • Core Mat is a low density non-woven laminate used to save weight, stiffen and thicken laminates. The material has excellent wet out and conformability. Core Mat is available in numerous styles and thicknesses (2-6mm).
  • KKK offers durable and lightweight honeycomb core panels optimal for structural applications.
  • KKK offer a variety of certified marine grade plywood for boat building and projects that require excellent water-resistant quality.
  • PET Foam is a sustainable core material that has superior mechanical properties, has outstanding fatigue resistance, easy to process and has excellent insulation properties. Brands Available - ArmaForm (Armacell), 100% recyclable
  • KKK's PU foam consists of a 2-component-system known as A & B for the production of closed cell rigid foam. It has excellent thermal properties and is widely used for insulation of tanks.
  • Rigid PVC foam is available in a range of densities and thicknesses to meet required specifications.  Sheets are also available as plain sheet, perforated etc. Brands Available - Divinycell (DIAB), Gurit etc.
  • Rigid Polyurethane Foam can be used in commercial and industrial applications within the service temperature range of -183°C to +105°C. These applications include insulation of pipes, tanks, fittings inside containers, trucks, boats as well as for architectural and structural panels as a core material.
