Self-extinguishing cable and fire retardant composition used therein

   
   

A fire-retardant composition includes a base polymer composition, including a polymer base material; melamine or a melamine derivative; red phosphorus; magnesium hydroxide or hydrated oxide, aluminum hydroxide or hydrated oxide, or magnesium hydroxide or hydrated oxide and aluminum hydroxide or hydrated oxide; and zeolite. The melamine or melamine derivative includes amounts between 5 and 50 parts-by-weight, inclusive. The red phosphorus includes amounts between 5 and 50 parts-by-weight, inclusive. The magnesium hydroxide or hydrated oxide, aluminum hydroxide or hydrated oxide, or magnesium hydroxide or hydrated oxide and aluminum hydroxide or hydrated oxide includes amounts between 10 and 150 parts-by-weight, inclusive. The zeolite includes amounts between 1 and 5 part-by-weight, inclusive. A self-extinguishing cable, including at least one conductor and at least one coating layer is also disclosed. The at least one coating layer includes the fire-retardant composition.
