On the way to a new and better glue for bookbinders, a new adhesive system was introduced for the first time in 1985. The base for this system is polyether or polyester, whereas polyurethane (PUR) is used as prepolymer. Its special features are coagulation at room temperature and resistance to moisture.

Also known as "fishy glue" this contact adhesive is commonly used when sticking a variety of materials, such as paper, board, upholstery, and carpet. It is used widely by model makers as a "mask" to protect areas during airbrushing. It can be used as an alternative to Table Tennis glue.
Cut pile rugs are softer but require carpet glue for stability. In contrast, loop pile rugs does not have to be glued. [7] After tufting, the pile can be sheared or cut using electric shearers or scissors to tidy and sculpt the yarn for the finished product. This can be done either before or after the latex glue is applied to the backing.
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.
Although many classes of fibers based on synthetic polymers have been evaluated as potentially valuable commercial products, four of them - nylon, polyester, acrylic and polyolefin - dominate the market. These four account for approximately 98 percent by volume of synthetic fiber production, with polyester alone accounting for around 60 percent ...
A carpet is a textile floor covering typically consisting of an upper layer of pile attached to a backing. The pile was traditionally made from wool, but since the 20th century synthetic fibers such as polypropylene, nylon, or polyester have often been used, as these fibers are less expensive than wool. The pile usually consists of twisted ...

Three ways to maximize the strength of a bond between the two flexible pieces are: Increase the area of the bond, e.g. using larger pieces. Ensure that the force is applied parallel to the plane of the fastener surface, such as bending around a corner or pulley. Increase the number of hooks and loops per area unit.
