Abstract: The invention provides a flame-retardant waterborne polyurethane dispersion. The dispersion includes: 1 to 15 parts by weight of a phosphorus flame retardant containing active hydrogen; 10 to 40 parts by weight of a diisocyanate; 30 to 80 parts by weight of a polyol; and 1 to 15 parts by weight of an active hydrogen-containing compound, which is capable of forming a hydrophilic group.

Abstract: A water-vapor permeable film. The film includes 90˜99 wt % polyurethane (PU) and 1˜10 wt % polyethylene (PE). The invention also provides a textile including the film.

Abstract: Disclosed is a co-extruded water-proof and moisture-permeable film structure, including a top skin layer, a core layer, and a bottom skin layer. The top and bottom skin layers include polyolefin or polyurethane and the core layer comprise polyurethane. The core layer is disposed between the top and bottom skin layers. If polyurethane is adopted in top and/or bottom skin layers, the polyurethane of the skin layers has lower moisture and vapor permeability than the polyurethane of the core layer. The described film can be manufactured by co-extruded bubble blown or co-extruded casting. In addition, the film can be laminated to a fabric to form a water-proof and moisture-permeable textile.

Abstract: Disclosed are high performance aqueous polyurethanes and methods of making the same. The aqueous polyurethane is prepared by prepolymerizing the following components (a), (b), and (c) in the absence of aliphatic or cycloaliphatic diisocyanates; and chain-extending the hydrophilic prepolymer with component (d): (a) 10-40 wt % of an aromatic diisocyanate consisting of toluene diisocyanate (TDI); (b) 1-15 wt % of a compound containing active hydrogen and a hydrophilic group or a group capable of forming hydrophilicity; (c) 30-80 wt % of a polyol; and (d) 0.1-5 wt % of a chain extender having active hydrogen. The aqueous dispersions of the polyurethane have good storage stability and the dried films produced therefrom possess superior mechanical properties.
