BALTEK SB is a core material produced from select kiln-dried balsa wood in the endgrain configuration. When balsa wood is cut perpendicular to the grain direction it has optimum physical properties due to its honeycomb-like cell structure.


  • Extremely low specific weight
  • High mechanical rigidity and stiffness
  • Reduced use of raw materials
  • Applications:

    Ship and boat construction (hull, decks, bulkheads, superstructures, interior fittings)
  • Compatible with polyester, vinylester or epoxy resins and glass, DuPont™ KEVLAR® or carbon fibers
  • Sandwich structures with balsa result in a particularly lightweight and sturdy end product

Depending on processing and in combination with other layers, BALTEK®core material has other interesting properties:

  • Excellent flexural,bond & shear strengths
  • High strength-to-weight ratio
  • Requires less resin to wet out than cellular foam cores
  • Pre-wetting not necessary
  • Certified & approved for marine use
  • Includes fiberglass scrim for contour ability
  • High specific stiffness and rigidity
  • Excellent fire behavior
  • Excellent moisture resistance
  • Excellent fatigue resistance
  • Excellent sound absorption and thermal insulation
  • High impact resistance
  • Operating temperature from -212° C to +163° C


  • Balsa is a universal core material due to the excellent styrene and chemical resistance as well as the neutral behavior in terms of temperature fluctuations
  • Balsa can be processed with all known resin systems and processes and has excellent laminate adhesion properties
  • BALTEK balsa wood is grown on their own plantations in Ecuador; it is not obtained from the deforestation of the rain forest
  • Ecological, sustainable product, made of 100% plantation wood

Other Applications:

  • Rail and road vehicles (floor, side and roof panels, front and side covering, interior fittings)
  • Wind energy plants (rotor blades, covers for rotor hubs,casings and generators)
  • Aerospace (floor plates, galley parts,interior fittings, transport pallets, containers, and structural parts of sporting aircraft)
  • Military applications (transport pallets, containers, shelters, boats)
  • Industrial components (containers, covers, tanks, sports equipment [skis, snowboards, kayaks])
