2. List of polyurethane applications - Wikipedia

   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. Moisture cure polyurethane - Wikipedia

   en.wikipedia.org/wiki/Moisture_cure_polyurethane

   Moisture cure polyurethanes have been widely used in the adhesive and coating industries. Thermal, mechanical, and surface properties of hyperbranched polyurethane-urea (HBPU) moisture cured coatings have been studied in relationship to chemical structure. [3]

4. Polyurethane - Wikipedia

   en.wikipedia.org/wiki/Polyurethane

   The properties of a polyurethane are greatly influenced by the types of isocyanates and polyols used to make it. Long, flexible segments, contributed by the polyol, give soft, elastic polymer. High amounts of crosslinking give tough or rigid polymers. Long chains and low crosslinking give a polymer that is very stretchy, short chains with many ...

5. 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.

6. Adhesive - Wikipedia

   en.wikipedia.org/wiki/Adhesive

   Adhesive, also known as glue, cement, mucilage, or paste, [1] is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. [2] The use of adhesives offers certain advantages over other binding techniques such as sewing, mechanical fastenings, and welding. These ...

   In 1994, during a trip to Indonesia, Mark Singer saw Danish-made polyurethane glue being used to make teak furniture. After returning to the US, he founded the company, created the brand name Gorilla Glue, and then acquired the North American rights for the glue from the Danish manufacturer. [1]

   Construction adhesive being used to attach an access panel to drywall. 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 ]

9. Polyurethane dispersion - Wikipedia

   en.wikipedia.org/wiki/Polyurethane_dispersion

   Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.
