Composition of polyvinyl chloride resin, composition of polyvinyl chloride resin composition, insulated wire and cable

摘要

PROBLEM TO BE SOLVED: To provide a polyvinyl chloride resin composition which satisfies flame retardancy conforming a combustion test for railway vehicle, and is excellent in a balance among cold resistance, electric insulation property and oil resistance, and a sheet, an insulated wire and a cable using the same.;SOLUTION: A polyvinyl chloride resin composition contains a polyvinyl chloride resin (A) having a K value of 69-79 and a partially crosslinked polyvinyl chloride resin (B), or the partially crosslinked polyvinyl chloride resin (B), diisononyl phthalate (C) and aluminum hydroxide (D) having an element mass concentration of sodium, calcium and potassium of 0.2 mass% or less, where an isononyl alcohol raw material having a specific composition is used in a raw material of the component (C), a mass ratio (A)/(B) of the component (A) to the component (B) is 0 to 60/40 to 100, the component (D) is 15-35 pts.mass with respect to 100 pts.mass of the sum of the component (A) and the component (B), and the total amount of the resin composition is 170-200 pts.mass.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
