Abstract: A coated fabric comprising a fabric substrate and a coating thereupon, said coating comprising a plurality of layers wherein at least one of the layers comprises a polyester polyurethane having a Shore A hardness of at least 90 durometer, or a linear polyurethane elastomer formed from a polyol; a diisocyanate compound; a first extender component having a molecular weight of below about 500; and a second extender component; wherein the diisocyanate compound is initially reacted with the first extender component in a molar ratio of above 2:1 to form a modified diisocyanate component having a functionality of about 2 prior to reaction with the other components to provide relatively low temperature processing properties to the composition. Preferably, different layers of these polyurethanes are included.

Abstract: Thermoplastic synthetic polymeric compositions of certain polyurethanes, polyamides or chlorinated polyolefins, having processing temperatures in the range of about 150.degree. to 325.degree. F., can be modified by the addition of a millable thermoplastic polyurethane elastomer thereto to lower the processing temperature by 10.degree. to 30.degree. F. or more. This modification enables the thermoplastic composition to be processed on conventional calendering or extrusion equipment with a lesser amount of energy or with better performance. Also, coated fabrics of such thermoplastic compositions and a fiber reinforcement.

Abstract: An improved high-intensity roto-peen flap, constructed of coated fabric material, the coating including a plurality of layers at least one of which comprises a linear polyurethane elastomer, exhibits improved life over previous high-intensity roto peen flaps. A method of making such a flap, a wheel incorporating at least one of the flaps, and a method of high-intensity roto-peening using the wheel are also presented.

Abstract: The processing temperature of linear thermoplastic polyurethane elastomers prepared from a polycarbonate polyol, a polyether polyol, an extender and a disocyanate compound which has been modified by reaction with a low molecular weight diol to form a modified diisocyanate compound prior to reaction with the other components of the elastomer, can be reduced by adding a millable thermoplastic linear polyurethane elastomer thereto. These materials possess an optimum combination of hydrolytic stability, toughness, flexibiity and low temperature processing characteristics.

Abstract: A fabric substrate which is at least partially or selectively coated with a novel polycarbonate-polyether polyurethane for use as a driver's side or passenger side air bag. The polyurethane coating is applied in a manner which provides a desired permeability to the fabric, allows the fabric to be cut without fraying the fibers of the substrate, and imparts flexibility toughness and tear resistance to the final product.
