FLAME RETARDANT, THERMOPLASTIC POLYCARBONATE MOLDING COMPOSITIONS |
摘要 |
A flame-retardant thermoplastic molding composition is disclosed. The composition contains aromatic polycarbonate resin, about 0.01 to 0.15 wt.-% of a salt, wherein the salt is an alkali metal or alkaline earth metal salt of perfluoroalkane sulfonic acid, aromatic sulfimide, ar aromatic sulfonic add, and about 0.5 to 10 wt.-% of poly- and/or oligo-aryloxysiloxane (herein after referred as aryloxysiloxane) as flame-retardant synergist. The inventive composition is characterized in that its flammability rating is better than that of aromatic polycarbonate resin containing only inorganic salt of a derivative from aliphatic or aromatic sulfonic acid, sulphonamide or sulfonimide in accordance with UL-94 V standard, while mechanical and optical properties of the compositions are maintained. |
