Polyurethane (PU), also known as Polyurethane Laminate (PUL), is a fabric laminate that is produced by laminating different types of clothing fabric into a thin polyurethane film. The most commonly used type of fabric for this purpose are waterproof fabrics, like polyester but it can also be created using cotton or other naturally fibers.
Materials that have been laminated with polyurethane are used in different industries including automotive, medical and clothing. This type of fabric is lightweight and breathable. It is also robust and durable and clothes made out of this material are able to survive at up to a hundred times of being washed and dried in a machine. It also blocks moisture, allowing easy removal of stains. This type of fabric is commonly used in manufacturing life vests, air mattresses, boats, diapers, canopies and lunch bags.
