  • Flame retardant polyolefin compositions
    Patent number: 4567214
    Abstract: Flame retardant polyolefin compositions having improved smoke suppressant properties comprise(1) a polyolefin,(2) a compound of iron,(3) a compound of antimony,(4) a non-basic compound of magnesium, and(5) a chlorinated organic compound of the formula ##STR1## wherein Z is a tetravalent saturated cyclic radical having at least 4 carbon atoms which may be substituted by chlorine, bromine, fluorine or alkyl of 1 to 6 carbon atoms.
    Type: Grant
    Filed: September 14, 1984
    Date of Patent: January 28, 1986
    Assignee: Occidental Chemical Corporation
    Inventor: Charles S. Ilardo
  • Flame retardant polyamide compositions
    Patent number: 4504611
    Abstract: 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##
    Type: Grant
    Filed: August 1, 1983
    Date of Patent: March 12, 1985
    Assignee: Occidental Chemical Corporation
    Inventors: Charles S. Ilardo, James J. Duffy
  • Fire retardant polyamide
    Patent number: 4447572
    Abstract: 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.
