CABLES FORMED FROM HALOGEN-FREE COMPOSITIONS HAVING FIRE RETARDANT PROPERTIES

摘要

Cables including a fire-retardant composition are disclosed. The fire-retardant compositions include an oxygen-containing base polymer, a primary filler, and an antimony-containing secondary filler. The primary filler can be a metal hydroxide. The fire-retardant composition can be halogen-free and exhibit an elongation at break of about 150% or more. The cable passes the UL 1581 VW-1 flame.

主权项

1. A cable comprising:
one or more conductors; and a fire-retardant composition surrounding the one or more conductors, the fire-retardant composition comprising:
about 100 parts, by weight, of an oxygen-containing base polymer;from about 80 parts to about 175 parts, by weight, of a primary filler, the primary filler comprising a metal hydroxide; andfrom about 5 parts to about 20 parts, by weight, of a secondary filler, the secondary filler comprising an antimony compound; and wherein the fire-retardant composition is substantially halogen-free and exhibits an elongation at break of about 150% or more; and wherein the cable passes the Underwriter's Laboratory (“UL”) 1581 VW-1 flame test.
