Summarize this article for a 10 year old
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.
