摘要： Polycarbonate compositions containing a specific combination of additives achieve desirable flame retardance characteristics when used in thin wall polycarbonate articles. These compositions contain a polycarbonate/siloxane component, containing a polycarbonate siloxane copolymer, or a mixture of a polycarbonate siloxane copolymer and polycarbonate resin; a mineral filler; and a flame retardant. The composition contains at least 50% by weight of polycarbonate when the polycarbonate of the polycarbonate siloxane copolymer and any polycarbonate resin (linear or branched) are considered together; and the polycarbonate siloxane copolymer and the mineral filler are present in amounts effective to achieve a flex modulus of 29,000 kg/cm3 or greater, for example 30,000 kg/cm3 or greater, good flex-fold strength and good impact strength, for example a room temperature Notched Izod Impact Strength of 25 kgf-cm/cm or greater. The composition also includes a flame retardant to enable the composition to obtain a UL94 rating of V0 at test thicknesses of 1.2 mm.

摘要： A material and method for making long fiber filled thermoplastics with improved additive evenness and physical properties that includes a fiber-filled thermoplastic resin and a coating layer that contains the one or more additives to eventually be dispersed in the molded article. The coating layer is added in a manner such that the coating does not substantially intermix with the thermoplastic resin to form the long fiber-filled thermoplastic material. The long fiber-filled thermoplastic material may then formed into a molded article using the long glass fiber-filled thermoplastic material. Since the long fiber-filled thermoplastic material is not formed into pellets prior to formation into the article, the problems associated with prior art methods regarding dispersion of the additives are avoided and the resulting molded article has improved additive evenness and characteristics as compared to prior art molded articles formed from a dry blend of pellets.
摘要翻译：一种用于制造长纤维填充热塑性塑料的材料和方法，其具有改进的添加剂均匀度和物理性能，其包括填充纤维的热塑性树脂和包含一种或多种添加剂以最终分散在模塑制品中的涂层。添加涂层的方式使得涂层基本上不与热塑性树脂混合以形成长纤维填充的热塑性材料。然后将长纤维填充的热塑性材料用长玻璃纤维填充的热塑性材料制成成型制品。由于长纤维填充的热塑性材料在形成制品之前不形成颗粒，因此避免了与现有技术中关于添加剂分散的方法相关的问题，并且与现有技术相比，所得到的模制品具有改进的添加剂均匀度和特性由颗粒的干混合物形成的模制品。
