Title (EN) NON-INFLAMMABLE POLYMER MIXTURE FREE FROM HALOGEN AND USE THEREOF
(FR) MELANGE POLYMERE LIBRE D"HALOGENE ET NON-INFLAMMABLE, AINSI QUE SON UTILISATION
Abstract: front page image
(EN)These mixtures of polymers free from halogen, on the basis of copolymers of acrylic olefins and esters, rubber of ethylen-acrylates, rubber of acrylates or the mixtures thereof or the mixtures with other polymers contain, out of 100 parts of mixture, 90 to 200 parts, particularly 120 to 180 parts, of aluminium oxide hydrate; the latter is prepared by precipitation and presents particles of 6(Alpha)n at the most, a specific surface over 6m2/g and contains - related to the quantity of aluminium oxide - more than 0.25% of sodium oxide, included at least 0.05% of soluble sodium oxide. Such mixtures of polymers have characteristics of non-inflammability, resist to the action of oils and solvents, as well as to sea water, while showing good mechanical characteristics. They can be used for making up insulating materials, for filling or sheathing electrical cables or for the preparation of coverings of floors or walls, as well as for the preparation of most diverse technical articles.
(FR)Ces melanges de polymeres libres d"halogene, sur la base de copolymeres d"olefines et d"esters acryliques, caoutchouc d"ethylene-acrylates, caoutchouc d"acrylates ou de leurs melanges ou de melanges avec d"autres polymeres, contiennent sur 100 parties de melange de base 90 a 200 parties, en particulier 120 a 180 parties, d"hydrate d"oxyde d"aluminium; ce dernier est prepare par precipitation et presente des particules d"au plus 6 (Alpha)m de grandeur, une surface specifique de plus de 6 m2/g et contient - rapporte a la quantite d"oxyde d"aluminium - plus de 0,25% d"oxyde de sodium, y compris au moins 0,05% d"oxyde de sodium soluble. De tels melanges de polymeres presentent des qualites de non-inflammabilite, resistent a l"action d"huiles et de solvants, ainsi qu"a l"eau de mer, tout en ayant de bonnes qualites mecaniques. Ils sont utilisables pour la confection de matieres isolantes, de remplissage ou d"emmanchement de cables electriques ou pour la preparation de revetements de sol ou de parois, ainsi que pour la preparation d"articles techniques les plus divers.
