Polyurethane laminate

Polyurethane laminate (PUL, thermal stretch,^[1] fuzzy rubber^[1]) is a compound fabric made by laminating a cloth fabric to one or both sides of a thin film of polyurethane.^[1]^[2] Polyurethane laminated fabrics have a wide range of applications in medical, automotive and garment uses.^[2]

Most PUL fabric is made by laminating lightweight polyester interlock knit fabric to a 1mm thick film of polyurethane. There are two processes used for lamination: solvent lamination, which fuses the fabric and polyurethane film into a single monolithic fabric, and hot melt, which uses heat-activated glue to adhere the fabrics together.^{[citation needed]} Woven fabric and fleece fabric can also be used,^[1] but a stiff fabric will drastically reduce the elasticity of the finished laminate.
