Abstract
Flame retardant, abrasion resistant elastomeric compositions comprised of thermoplastic polyurethane polymer and flame retarding amounts of a filler selected from decabromodiphenyloxide and antimony oxide in a 3:1 weight ratio, and decabromodiphenyloxide, antimony oxide, and ammonium polyphosphate in a 3:1:3 weight ratio respectively. Also, flame retardant, abrasion resistant, and heat sealable coated fabrics employing such elastomeric compositions as coating film.

A flexible, abrasion resistant, flame retardant coated fabric capable of being joined by heat or dielectric sealing procedures which coated fabric comprises a fabric substrate, selected from the group consisting of the woven, knitted and bonded web fabrics of synthetic and natural fibers, bonded to a flame retardant coating of an elastomeric composition comprising about 30 to about 60 wt. percent of a soluble, thermoplastic polyurethane and from about 70 to about 40 weight percent of a flame retardant additive selected from the group consisting of decabromodiphenyloxide and antimony oxide in a weight ratio of about 3:1, respectively, and decabromodiphenyloxide, antimony oxide and ammonium polyphosphate in a weight ratio of about 3:1:3, respectively.
A flame retardant coated fabric capable of being joined by heat sealing which comprises a fabric substrate bonded to a flame retardant polymer film which does not possess heat sealing characteristics, and a coating, bonded to said polymer coating, of an elastomeric composition comprising about 30 to about 60 wt. percent soluble, thermoplastic polyurethane and about 70 to about 40 wt. percent of a flame retardant additive selected from the group consisting of decabromodiphenyloxide and antimony oxide in a weight ratio of about 3:1, respectively, and decabromodiphenyloxide, antimony oxide, and ammonium polyphosphate in a weight ratio of about 3:1:3, respectively.
A method for producing a flame retardant, abrasion resistant coated fabric capable of being heat sealed, which method comprises:
- bonding to a fabric substrate a coating of an elastomeric composition comprising about 30 to about 60 wt. percent of a soluble, thermoplastic polyurethane and about 70 to about 40 weight percent of a flame retardant additive selected from the group consisting of decabromodiphenyloxide and antimony oxide in a weight ratio of about 3:1, respectively, and decabromodiphenyloxide, antimony oxide and ammonium polyphosphate in a weight ratio of about 3:1:3, respectively.
