Problems solved by technology
However, although the polyarylene sulfide resin composition and its molded product can improve silicone adhesiveness, the mold release property during molding is not sufficient. For example, when the mold is opened after injection molding, the molded product sticks to the mold ( The fixed side) has a high frequency, which causes damage to the Z-shaped part of the molded product formed by the hook pin (Z pin)

[0102] According to the composition components and compounding quantity described in Table 1-2, each material was uniformly mixed with the tumbler. Then, the above-mentioned compounding material was put into the twin-screw extruder "TEM-35B" with a vent hole manufactured by Toshiba Machine Co., Ltd., and the discharge amount of the resin component was 25kg / hr, the screw speed was 250rpm, and the discharge amount of the resin component (kg / hr) to the screw rotation speed (rpm) (discharge amount / screw rotation speed) = 0.1 (kg / hr·rpm), melt kneading at a set resin temperature of 330°C to obtain pellets of polyarylene sulfide resin composition .
[0103] The following various evaluation tests were performed using this pellet. The results of the test and evaluation are shown in Tables 1-2.
