Abstract: front page image
(EN)The invention provides, in one aspect, a brush seal comprising brush seal bristles made up of component brush seal filaments. The component brush seal filaments comprise a polyether ketone comprising structural units derived from a diaryl ketone and a diphenolic compound and having a glass transition temperature in excess of 100°C. In a particular embodiment, the component brush seal filaments comprise PEEK. The novel brush seals provided by the present invention present a number of advantages over conventional non-metallic brush seals comprising KEVLAR filaments, such as enhanced friction characteristics and greater stability to fluid lubricants comprising groups reactive with the amide moieties present in aramid filaments such as KEVLAR.
(FR)Sous un de ses aspects, l'invention propose un joint brosse comprenant des poils de joint brosse composés de filaments constitutifs de joint brosse. Les filaments constitutifs de joint brosse comprennent une polyéthercétone comprenant des unités structurales issues d'une diarylcétone et d'un composé diphénolique ayant une température de transition vitreuse dépassant 100°C. Dans un mode de réalisation particulier, les filaments constitutifs de joint brosse comprennent de la PEEK. Les nouveaux joints brosse fournis par la présente invention présentent un nombre d'avantages sur les joints brosse non métalliques classiques comprenant des filaments de KEVLAR, tels que des caractéristiques de frottement améliorées et une stabilité augmentée aux lubrifiants fluides comprenant des groupes capables de réagir avec les fractions amides présentes dans les filaments d'aramide tels que le KEVLAR.
