3A Composites Core Materials AIREX® T90.210 Easy Processing Structural FST Foam
Categories: Other Engineering Material; Composite Core Material; Polymer; Thermoplastic

Material Notes: AIREX® T90 is a closed-cell, thermoplastic and recyclable polymer foam with excellent fire, smoke & toxicity (FST) properties. It has good mechanical properties and resistance to fatigue, is chemically stable, UV-resistant and has negligible water absorption. It is thermally stable during high temperature processing and post curing without after expansion or outgassing. T90 is designed for easy use with all resin systems and processing technologies. AIREX® T90 is the ideal core material for structural sandwich applications requiring high fire resistance.
