Outgassing of High-Temperature-Resistant Organic Polymeric Materials for Possible Shipboard Use.

摘要

Four polymeric materials, polyphenylene oxide, polyquinoline, acetylene substituted polyimide, and polybenzimidazole, reported to possess high-tempeature resistance, were investigated in order to determine their outgassing characteristics as related to their suitability for shipboard applications. The materials were sequentially exposed to 150, 250, and 450 C for 3-hour periods and the types and amounts of their outgassed products were determined. The amounts of outgassed products were small from polyquinoline, acetylene substituted polyimide, and polybenzimidazole. It was concluded that those materials would be suitable for use in shipboard applications where high-temperature resistance (up to 450 C) is required, providing that normal ventilation is available. The quantity of outgassed products from polyphenylene oxide was too great to consider that material suitable for shipboard applications requiring high-temperature resistance. (Author)
