    • 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.
    • 改进,成熟,阻燃,可成型四组分热固性塑料聚酯树脂体系。 在组合物中使用两种不同的聚酯树脂。 该组合物含有羟基与羧基的比例为5.7至0.8,酸值至少为18,平均分子量为约800至5,000的相对较快反应的不饱和聚酯树脂。 聚酯的存在量为组合物重量的约5-15%。 存在第二不饱和聚酯树脂,其羟基与羧基的比例为5.7至0.8,酸值为约8至17,平均分子量为约800至5,000。 第二聚酯的存在量为约5至15重量%。 第四组分是约1至4重量%存在的溴化不饱和聚酯树脂。 该系统还含有35-45%的三水合铝和0.5-2%(重量)的三氧化二锑。 还存在惰性填料,例如增强纤维或惰性无机材料。
