Problems solved by technology
However, there is a problem with a resin composition using a phosphate ester flame retardant in that the so-called "juicing" phenomenon, which means that migration of the flame retardant during molding and deposition on the surface of the molded body occurs, Therefore the resin composition suffers from a sharp deterioration in heat resistance
However, this can lead to deterioration of rigidity

[0114] According to the compositions and amounts as listed in Table 1, the components were introduced into a 32L / D twin-screw type extruder having a diameter of 45mm, and then melted and extruded at 240°C to 280°C to prepare pellets. The prepared pellets were dried at 80°C for 5 hours or more, and then injection molded at 240°C to 280°C using a 3oz screw type injection molding machine to prepare samples. The prepared samples were evaluated for the following properties, and the results are shown in Table 1.
[0115] performance evaluation
[0116] (1) Flame retardancy level: The flame retardancy level was measured on a 1.2 mm thick sample according to the UL-94 vertical flammability test method.
[0117] (2) Vicat softening temperature (VST, unit: °C): Vicat softening temperature is measured under a load of 5 kgf according to ASTM D1525.
[0118] (3) Izod impact strength (unit: kgf·cm / cm): Izod impact strength was measured on a notched Izod sample with a thickness of 1 / 8" acc...
