Description du produit<\/b><\/strong><\/span><\/p>\n

Se distinguant par ses attributs sup\u00e9rieurs par rapport \u00e0 l'huile de m\u00e9thylsilicone, notre produit offre une r\u00e9sistance am\u00e9lior\u00e9e aux basses temp\u00e9ratures, une isolation \u00e9lectrique sup\u00e9rieure et une cha\u00eene de carbone \u00e9thyle plus longue, ce qui se traduit par une compatibilit\u00e9 sup\u00e9rieure avec les solvants organiques. Fonctionnant dans une plage de temp\u00e9ratures de -60\u00b0C \u00e0 150\u00b0C, il pr\u00e9sente un coefficient temp\u00e9rature-viscosit\u00e9 minimal, ainsi que des performances lubrifiantes et di\u00e9lectriques exceptionnelles. Caract\u00e9ris\u00e9 par une faible volatilit\u00e9, une faible tension superficielle, une non-toxicit\u00e9, une non-corrosivit\u00e9 et des propri\u00e9t\u00e9s anti-\u00e2ge, il peut \u00eatre m\u00e9lang\u00e9 \u00e0 diff\u00e9rentes viscosit\u00e9s pour r\u00e9pondre aux exigences d'application sp\u00e9cifiques.<\/span><\/p>\n
