The amount of stabilizer added is preferably 2 to 5 parts by weight per 100 parts by weight of CPVC. If the amount of the stabilizer is less than 2 parts by weight, the thermal stability of CPVC is significantly reduced, which is not preferable. On the other hand, if the amount of the stabilizer exceeds 5 parts by weight, the effect of the thermal stability will reach a ceiling and the thermal stability corresponding to the added amount will not be obtained, which is not preferable.

The amount of the lubricant blended is preferably 2 to 4 parts by weight with respect to 100 parts by weight of CPVC. If the amount of the lubricant is less than 2 parts by weight, the melt viscosity will be high and the extrudability will be poor, which is not preferable. On the other hand, if the amount of the lubricant exceeds 4 parts by weight, the slipperiness between the resin and the metal becomes too strong, and pulsation may occur in the resin discharge during extrusion, which is not preferable.
