Title (EN) FLAME RETARDANT MOLDING COMPOUND
(FR) PATE DE MOULAGE RESISTANTE AUX FLAMMES
Abstract: front page image
(EN)Improved, matured, flame resistant, moldable four component thermosetting plastic polyester resin system. Two different polyester resins are used in the composition. The composition contains a relatively fast reacting unsaturated polyester resin having a ratio of hydroxy to carboxyl groups of 5.7 to 0.8, and acid number of at least 18 and an average molecular weight of about 800 to 5,000. The polyester is present in an amount of about 5-15 percent by weight of the composition. A second unsaturated polyester resin is present having a hydroxyl to carboxyl ratio of 5.7 to 0.8, an acid number of about 8 to 17, and an average molecular weight of about 800 to 5,000. The second polyester is present in an amount of about 5 to 15 weight percent. The fourth component is a brominated unsaturated polyester resin present in about 1 to 4 weight percent. The system also contains 35 to 45 percent of aluminum trihydrate and 0.5 to 2 percent by weight of antimony trioxide. Also present are inert filler materials such as reinforcing fibers or inert inorganic materials.
(FR)Systeme de resine polyester plastique a thermoprise a quatre composants moulables, resistant aux flammes, vieilli et ameliore. Deux resines de polyester differentes sont utilisees dans la composition. La composition contient une resine polyester non saturee a reaction relativement rapide ayant un rapport entre les groupes hydroxy et carboxyles de 5,7 a 0,8, et un nombre acide d'au moins 18 et un poids moleculaire moyen d'environ 800 a 5000. Le polyester est present en une quantite d'environ 5-15% en poids de la composition. Une seconde resine polyester non saturee est presente avec un rapport hydroxyle-carboxyle de 5,7 a 0,8, un nombre acide d'environ 8 a 17, et un poids moleculaire moyen d'environ 800 a 5000. Le second polyester est present en une quantite d'environ 5 a 15% en poids. Le quatrieme composant est une resine polyester non saturee bromee presente dans la proportion de 1 a 4% en poids environ. Le systeme contient egalement 35 a 45% de trihydrate d'aluminium et 0,5 a 2% en poids de trioxyde d'antimoine. Des materiaux de remplissage inertes sont egalement presents tels que des fibres de renforcement ou des materiaux inorganiques inertes.
