   en.wikipedia.org/wiki/List_of_polyurethane...

   Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

3. Polyurethane - Wikipedia

   en.wikipedia.org/wiki/Polyurethane

   Chain extenders (f = 2) and cross linkers (f ≥ 3) are low molecular weight hydroxyl and amine terminated compounds that play an important role in the polymer morphology of polyurethane fibers, elastomers, adhesives, and certain integral skin and microcellular foams. The elastomeric properties of these materials are derived from the phase ...

4. Moisture cure polyurethane - Wikipedia

   en.wikipedia.org/wiki/Moisture_cure_polyurethane

   Moisture cured polyurethane–urea coatings have been made by reacting 1,2,3-triazole rich polyether polyols with HMDI at NCO/OH eq. ratio of 1.2 to obtain isocyanate-terminated polyurethane prepolymers. The prepolymers were cured under atmospheric moisture to make polyurethane–urea free films.

   The FTC alleged "that certain labels and marketing materials may have overstated the extent to which Gorilla Glue adhesive products are made in the United States", because many of the raw materials were sourced overseas first. [8] Due to Gorilla Glue's stated intent to correct this marketing issue, the FTC decided not to take further action. [8]

   The construction adhesive is in a caulking gun at the top of the image. Construction adhesive is a general-purpose adhesive used for attaching drywall, tile, molding, and fixtures to walls, ceilings, and floors. [1] It is most commonly available in tubes intended for use with a caulking gun. [2]

7. Thermoplastic polyurethane - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_polyurethane

   Thermoplastic polyurethane (TPU) is any of a class of polyurethane plastics with many properties, including elasticity, transparency, and resistance to oil, grease, and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
