ULTRATECT is a new High-Performance- PES-foam with unique properties especially appropriate for use as sandwich core. Due to its Microhoneycomb-structure and excellent properties of its basic polymer Polyethersulfon, sandwich-structures with ULTRATECT benefit from high strength and toughness. ULTRATECT finally is the "missing link" for a complete range of ultra-light-weight Thermo- plastic Technology! Speciality: Sandwich-structures with mono- polymer PES-core / PES-face-laminates.
