Title:
FLAME-RETARDANT VINYL CHLORIDE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2023183000
Kind Code:
A
Abstract:
To provide a flame-retardant vinyl chloride resin composition that exhibits superior flame retardancy with an oxygen index of 40% or more, and demonstrates hardness suitable for coating wires and cables.SOLUTION: A flame-retardant vinyl chloride resin composition contains a vinyl chloride resin, a plasticizer, and an inorganic flame retardant. Relative to 100 pts.mass of the vinyl chloride resin, the content of the plasticizer is 35-60 pts.mass and the content of the inorganic flame retardant is 70-100 pts.mass. The plasticizer is a mixture of general plasticizer and flame-retardant plasticizer. Relative to the total content of the mixture, the content of the flame-retardant plasticizer is 45 mass% or more. An oxygen index, as measured in accordance with JIS K 7201-2, is 40 or more.SELECTED DRAWING: None
