Polyurethane laminate

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

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. Woven fabric and fleece fabric can also be used, but a stiff fabric will drastically reduce the elasticity of the finished laminate.
