Embodiment 1
[0226] 89.5 parts by mass of PPS, 5 parts by mass of PPE, 5 parts by mass of modified elastomer 1, and 0.5 parts by mass of a silane coupling agent were uniformly mixed with a drum mixer to obtain a mixture.
[0227] Next, this mixture was injected|thrown-in to the twin-screw extruder (The Nippon Steel Works make, "TEX-30α") equipped with a belt. Then, it was melt-extruded under conditions of a discharge rate of 20 kg / hr, a screw speed of 300 rpm, and a set temperature of 300° C., discharged in a strand form, cooled with water at a temperature of 30° C., and then cut to produce a resin composition.
[0228] Next, this resin composition was injected|thrown-in to the single-screw extruder of full flight screw, and it melt|melted on the condition of 280-300 degreeC. After the molten resin composition was extruded from the T-die, it was cooled in close contact with a cooling roll set at 40° C. to produce an unstretched sheet.
[0229] Next, the prepared unstretched sheet was bi...
Embodiment 2
[0234] The compounding quantity of PPS was made into 86.5 mass parts, and except having added 3 mass parts of styrene-type resin 1 further, it carried out similarly to Example 1, and manufactured the flat cable.
[0235] In addition, when the constituent components of the insulating film were analyzed by the same method as in Example 1, it was found that the particles of PPE were dispersed in the matrix of PPS. It should be noted that the modified elastomer 1 exists alone as dispersed particles, or exists at the interface between the matrix and the PPE particles.
Embodiment 3~5
[0237] A flat cable was produced in the same manner as in Example 2, except that the compounding amounts of PPS, PPE, modified elastomer 1, styrene-based resin 1, and the silane coupling agent were changed as shown in Table 2.
[0238] In addition, when the constituent components of the insulating film were analyzed by the same method as in Example 1, it was found that the particles of PPE were dispersed in the matrix of PPS. It should be noted that the modified elastomer 1 exists alone as dispersed particles, or exists at the interface between the matrix and the PPE particles.
