In accordance with the present invention, it has been discovered that free standing lubricant additive gels can "provide additives to a functional fluid over time, wherein the free standing gel comprises at least two of the following components: a basic component, an acidic component, a polyolefin mixture, and optionally at least one additional additive and wherein these free standing gels have tan delta values of less than 0.330 and cone pen value of less than 75. These free standing gels release at least one desired additive into a functional fluid over time when the gel is contacted with the functional fluid and also can be removed from its forming container while retaining its shape and dimensional integrity, and can be inserted into a delivery device without the need for a containment device.
L'invention concerne des gels additifs lubrifiants autonomes qui peuvent fournir des additifs à un fluide fonctionnel au cours du temps, le gel autonome comprenant au moins un ou deux des composants suivants : un composant basique, un composant acide, un mélange polyoléfinique, et éventuellement au moins un additif supplémentaire, et dans lequel ces gels autonomes ont des valeurs tan delta inférieures à 0,33, et des valeurs pen de pointe inférieures à 75. Ces gels autonomes libèrent au moins un additif souhaité dans un fluide fonctionnel au cours du temps lorsque le gel est mis en contact avec le fluide fonctionnel, et peuvent également être enlevés de leur récipient de formation tout en conservant leur forme et leur intégrité de dimension, et peuvent être introduits dans un dispositif de délivrance sans avoir besoin d'un dispositif de confinement.
