Kneading and extruding at about 0 ° C to make a string-like strand,
It is manufactured by pelletizing with a pelletizer after cooling. However, the glass fiber reinforced PBT resin molding material has poor tracking resistance. Therefore, in order to improve the tracking resistance of the glass fiber reinforced PBT resin molding material, a polymer alloy of PA resin and PBT resin is formed. Furthermore, the PA resin is used in combination with a modified polyolefin having a reactive functional group such as a modified PP resin having a silanol group, a carboxyl group or an epoxy group,
It is preferable to form a polymer alloy with the PBT resin.
That is, the PA was added to 100 parts by weight of the PBT resin.
Polymer alloy is carried out by adding 25 to 150 parts by weight of a resin and, if necessary, 5 to 75 parts by weight of a modified polyolefin having a reactive functional group. This makes it possible to obtain a PBT resin molding material that gives a molded product having a good balance of heat resistance, mechanical properties, and tracking resistance.
