1. Propri\u00e9t\u00e9 du produit<\/b><\/strong><\/h3>\n

L'\u00e9ther m\u00e9thylique du dipropyl\u00e8ne glycol (DPM) est un liquide clair et incolore avec une l\u00e9g\u00e8re odeur d'\u00e9ther. Il pr\u00e9sente d'excellentes propri\u00e9t\u00e9s de solubilit\u00e9, \u00e9tant miscible avec l'eau et la plupart des solvants organiques. Le compos\u00e9 est peu volatil (pression de vapeur : 0,3 mmHg \u00e0 20\u00b0C) et son point d'\u00e9bullition est \u00e9lev\u00e9 (190\u00b0C). Son caract\u00e8re hydrophile\/lipophile \u00e9quilibr\u00e9 en fait un agent de couplage efficace. Le DPM pr\u00e9sente une bonne stabilit\u00e9 chimique et est biod\u00e9gradable dans des conditions a\u00e9robies.<\/p>\n

3. Champ d'application et utilisation<\/b><\/strong><\/h3>\n

Le DPM est largement utilis\u00e9 comme solvant dans les rev\u00eatements, les encres et les formules de nettoyage en raison de son taux d'\u00e9vaporation \u00e9quilibr\u00e9 et de son pouvoir solvant. Il sert de composant actif dans les d\u00e9capants et les d\u00e9graissants. Ce produit chimique est utilis\u00e9 dans les liquides de nettoyage \u00e9lectronique et les applications de nettoyage de pr\u00e9cision. Dans les produits de soins personnels, il sert de solvant porteur pour les parfums. Le DPM est \u00e9galement utilis\u00e9 dans les formulations agricoles et comme interm\u00e9diaire pour la synth\u00e8se chimique. Son profil de faible toxicit\u00e9 le rend appropri\u00e9 pour les applications de produits de consommation lorsqu'il est utilis\u00e9 dans le cadre des directives recommand\u00e9es.<\/p>\n

4. Emballage et stockage<\/b><\/strong><\/h3>\n

Le DPM est g\u00e9n\u00e9ralement conditionn\u00e9 dans des f\u00fbts en acier de 200 litres, des conteneurs IBC de 1000 litres ou des citernes en vrac. Le stockage doit se faire dans des zones fra\u00eeches et bien ventil\u00e9es, \u00e0 l'\u00e9cart des sources de chaleur et des agents oxydants. Les conteneurs doivent \u00eatre maintenus herm\u00e9tiquement ferm\u00e9s pour \u00e9viter l'absorption d'humidit\u00e9. Le produit est stable dans des conditions normales et sa dur\u00e9e de conservation recommand\u00e9e est de 24 mois. Lors de la manipulation, utiliser des gants r\u00e9sistants aux produits chimiques et des lunettes de protection.<\/p>","protected":false},"excerpt":{"rendered":"
