AIREX® T92 - easy to process structural PET foam

AIREX® T92 is a thermoplastic structural rigid foam with closed cells and is highly suitable for lamination using all types of resins and processes. The AIREX® T92 manufacturing process results in a structural core material with very consistent properties. Shear strain/damage tolerance is highly improved and allows utilization in most structural sandwich constructions. The foam is very easy to process mechanically, can be thermoformed, and is very heat resistant. AIREX® T92 is ideal for use with various pre-preg systems at higher temperatures. It is very chemically stable, does not absorb water, and shows no post-expansion.

Applications
  • Wind energy plants (rotor blades [shear webs & shells] and gondolas)
  • Ship and boat construction (hull, deck, superstructures, stern, bulkheads, frames)
  • Industrial components (covers, containers, local reinforcements, x-ray tables, sports)
