Title (EN) USE OF POLYESTERS AS VISCOSITY INDEX IMPROVERS FOR AIRCRAFT HYDRAULIC FLUIDS
(FR) UTILISATION DE POLYESTERS COMME AMÉLIORANTS D'INDICE DE VISCOSITÉ POUR FLUIDES HYDRAULIQUES D'AÉRONEFS
Abstract:
(EN) The invention is related to a composition for use in hydraulic systems of an aircraft. The composition typically comprises an adipic acid-based polyester in a phosphate ester base stock substantially consisting of trialkyl phosphates.
(FR) L'invention concerne une composition destinée à être utilisée dans des systèmes hydrauliques d'un aéronef. La composition comprend typiquement un polyester à base d'acide adipique dans une réserve de base d'ester phosphorique essentiellement constituée de trialkylphosphates.
