This material was primarily developed for insulation of liquid H2 fuel tanks for launch vehicles. The material, which is referred to as an Inter-Polymer-Network, consists of a polymeric alloy of a highly cross-linked polyamide-urea and a ductile linear vinyl polymer. The cryogenic properties are good and the material exhibits excellent short-term capability at high temperatures. IPN 20-649 us thermo-formable. Information provided by DIAB, Inc. |
