Abstract

The invention relates to a semi-aromatic polyamide molding composition for an LED (light-emitting diode). The semi-aromatic polyamide molding composition for the LED comprises the following components: (A) 25-90 parts of at least one semi-aromatic polyamide resin; (B) 5 to 30 parts of glass fibers having an arithmetic average length of 200 [mu] m to 500 [mu] m; (C) 5 to 50 parts of a white pigment; (D) 0 to 40 parts of an additive. The semi-aromatic polyamide molding composition for an LED according to the present invention achieves a balance between water absorption performance and fluidity compared to a molding composition having glass fibers having an arithmetic average length of not more than 200 [mu] m to 450 [mu] m, so that a molded article prepared from the composition according to the present invention can be used in the fields of LED supports and the like having high dimensional stability requirements.

Description

technical field [0001] The present invention relates to semi-aromatic polyamide molding compositions for LEDs. 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 friction coefficient, certain flame retardancy, and easy processing. It is widely suitable for filling reinforcement and modification with glass fiber and other fillers to improve performance and expand the scope of application. In recent years, semi-aromatic polyamides have been mainly developed due to their better heat resistance and mechanical properties. [0003] LEDs are increasingly used as light sources due to their many advantages over conventional light sources. LEDs generally consume less power, require lower operating voltages, and have good resistance to mechanical shock than incandescent and other light sources. As a result, LED light sourc...
