Flame retardant polyolefin compositions having improved smoke suppressant properties comprise

Flame retardant polyolefin compositions

Polyamide compositions having improved flame retardant properties and arc tracking resistance comprises, in percent by weight, about 35 to about 76 percent polyamide; about 6 to about 10 percent zinc borate; about 10 to about 15 percent melamine cyanurate; 0 to about 35 percent glass fiber; about 0 to about 3 percent antimony trioxide; and about 8 to about 15 percent of a chlorinated compound of the formula: ##STR1##

Flame retardant polyamide compositions

Polyamides, flame retarded with a halogenated derivative and blended with a polymer blend resin being at least partially incompatible and having a lower melt viscosity than the polyamide, to improve the arc tracking resistance of the polyamide, are disclosed. The polyamides are particularly useful in the manufacture of flame retarded electrical components.

Fire retardant polyamide

Polyolefins such as polyethylene, polypropylene, and the like are rendered flame retardant by incorporating therein about 2-60 percent of a combination of (1) a Diels-Alder adduct of a chlorinated cyclopentadiene and a polyunsaturated cycloaliphatic compound and (2) a brominated aromatic compound.

Flame retardant polymer compositions

Flame retardant nylon compositions having improved physical properties and excellent molding characteristics comprise a mixture of about 45 to about 70 weight percent of nylon 6 or nylon 66 or mixture thereof; about 15 to about 25 percent of nylon 612; about 2 to about 10 percent of iron oxide, antimony oxide or zinc oxide or mixture thereof; and about 10 to about 25 percent of bis(hexachlorocyclopentadieno)cyclooctane.
