Easy to process FST structural foam

AIREX® T90 is a closed-cell, thermoplastic and recyclable, structural PET rigid foam with excellent fire, smoke and toxicity (FST) properties. It is suitable for lamination with all types of resins and processes. It is easy to thermoform and process mechanically. It also offers great chemical resistance, is resistant against UV rays and does not absorb water. Curing and post curing at increased temperatures are unproblematic as it is highly heat-resistant without showing post-expansion and outgassing.



  • Excellent fire inhibition (EN 45545; FAR 25.853)
  • Excellent fatigue resistance
  • Very easy processing with all resins and lamination processes
  • Excellent long-term thermostability up to 100°C
  • Very high processing temperature up to 150°C
  • High compression resistance and high compressive modulus
  • Very deep dispersion of mechanical values
  • Excellent face sheet adhesion (face sheet bond to core)
  • Excellent chemical resistance
  • No water absorption
  • No expansion
  • Recycled and recyclable material


  • Ship and boat construction: decks, interior fittings, superstructures
  • Rail and road vehicles: floor plates, sidewalls, interior fittings, roofs, motor covers
  • Industry: covers, containers, x-ray tables, sports
  • Building and construction: roofs, cover panels, domed roofs, portable structures


  • Hand lamination / spray lay-up
  • Vacuum infusion
  • Resin infusion / injection (VARTM / RTM)
  • Adhesive bonding
  • Prepreg processing
  • Molding processes (GMT, SMC)
  • Thermoformable
