Conductor: Coated Copper Insulation: Radiation Cross-linked Modified ETFE  Download pdf drawing |
ApplicationsMarmon’s AD50 is a Space-Grade wire with excellent properties across the board. The AD50 wire uses a proprietary blend of irradiation cross-linked Ethylene-Tetrafluoroethylene Copolymer (XL-ETFE) along with advanced material processing to create a low off-gassing (also called Fluoride Evolution) wire. AD50 wire is manufactured to meet the requirements of AS22759/32-46 as well as the extra requirements herein. |
