Abstract
Description
本発明は、少なくとも1種のポリスルフィド成分および少なくとも1種のポリチオエーテル成分を含有する、ポリマーブレンドに関する。
硫黄含有ポリマーは、それらの架橋の際の燃料抵抗特性に起因して、航空宇宙産業用のシーラントにおける使用のためによく適していることが、公知である。ポリスルフィドシーラントは、高い引張り強度、高い引き裂き強度、熱抵抗および高い紫外線に対する抵抗を提供する。このようなシーラントはまた、燃料に対する抵抗性を提供し、そして燃料への曝露の際に、それらの接着を維持する。
本発明は、少なくとも1種のポリスルフィド成分および少なくとも1種のポリチオエーテル成分を含有する、ポリマーブレンドに関する。このブレンドおよび硬化剤を含有するシーラントは、さらに、本発明の範囲内である。
本発明は、一般に、少なくとも1種のポリスルフィド成分および少なくとも1種のポリチオエーテル成分を含有する、ポリマーブレンドに関する。
