こなわれる。The amount of hydrophobic silica to be blended is from 1 to 30 parts by weight, preferably from 2 to 5 parts by weight, per 100 parts by weight of the thermoplastic resin. If the amount is less than 1 part by weight, no water resistance effect will be obtained, and if it is more than 30 parts by weight, the properties of the thermoplastic resin will be impaired.
