Abstract

The invention provides a flame-retardant reinforced semi-aromatic polyamide molding composition with a specific glass fiber length and a molded product. The flame-retardant reinforced semi-aromatic polyamide molding composition with the specific glass fiber length is composed of the following components: (A) 25 parts to 90 parts of at least one semi-aromatic polyamide resin; (B) 5 parts to 60 parts of glass fibers having an arithmetic mean length of 210 [mu]m to 450 [mu]m; (C) 5 parts to 40 parts of at least one brominated flame retardant and 0.1 part to 10 parts of at least one flame retardant aid; and (D) 0 part to 40 parts of an additive. The flame-retardant reinforced semi-aromatic polyamide molding composition having a specific glass fiber length has improved water absorption rate and dimensional stability after water absorption compared to a molding composition having the glass fibers having an arithmetic mean length of 230 [mu]m to 400 [mu]m or more; therefore, the molded product prepared from the molding composition can be used for specific applications in the electrical industry and the electronic industry, especially in the field with precision part requirements.

Description

technical field [0001] The polymer blend modification according to the invention relates in particular to a flame-retardant polyamide molding composition and also to moldings of this composition. Background technique [0002] Polyamide is widely used because of its good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubrication, low coefficient of friction, certain flame retardancy, and easy processing. It is suitable for filling and modifying with glass fiber and other fillers to improve performance and expand application range. In recent years, semi-aromatic polyamides have been focused on development due to their better heat resistance and mechanical properties. [0003] In some applications plastics are subject to stringent requirements related to their flame retardancy. Providing flame retardancy to plastics is especially necessary for use in electronic devices due to the risk of short circuits...
