Abstract

PURPOSE: To prepare the title composition having excellent flame-retardancy and suppressed melting and burning characteristics, and suitable as a sheath layer of an electric wire or cable, by compounding a vinyl chloride resin with a specific plasticizer, antimony trioxide, magnesium hydroxide, and calcium carbonate.
CONSTITUTION: A composition composed of (A) 100 parts by weight of a vinyl chloride resin, (B) 40W90 parts of a plasticizer containing ≥30wt% of a high- molecular weight plasticizer having a molecular weight of ≥900, (C) 3W50 parts of antimony trioxide, (D) 5W80 parts of magnesium hydroxide, and (E) 10W80 parts of calcium carbonate having maximum particle diameter of ≤250mμ. Use of a vinyl chloride resin having an average polymerization degree of ≥1,800, further improves the flame-retardancy by forming a tough and non-collapsible sheath layer when exposed to fire.
