An Overview of Polyurethane Fabric

Polyurethane Fabric. Polyurethane (PU) is a composite material made of: (1) one or more layers of polymer resins joined by urethane links; and (2) a woven or non-woven textile backing such as polyester, cotton, nylon, or ground leather. The PU coating is applied to a single side of the base fabric and then treated to look more like animal hide.

FAQ: Acrylic, Polyurethane and Silicone Proofing Techniques

Polyurethane coated fabric has coating of PU on one side of the fabric, as with an acrylic coating. The PU coating tends to be a bit thicker than an acrylic coating and looks slightly duller. It appears that PU coatings are more expensive in practice - although this may be influenced by the obvious fact that a thicker layer needs more polymer.

Waterproof Fabric Coatings 101: PU vs. PE vs. Silicone ...

PU coatings get in between the yarns, and lock them in place. This reduces slippage and consequently reduces the tear strength, making PU-coated fabrics slightly weaker than the fabric before coating. Long-term waterproofness is another area in which PU coatings have some drawbacks.
