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 ...

   A table green wood-stained and varnished with three layers of polyurethane varnish. Polyurethane varnishes are typically hard, abrasion-resistant, and durable coatings. They are popular for hardwood floors but are considered by some wood finishers to be difficult or unsuitable for finishing furniture or other detailed pieces. Polyurethanes are ...

6. Wood finishing - Wikipedia

   en.wikipedia.org/wiki/Wood_finishing

   Larger gouges and splits are best repaired by patching the void with a piece of wood that matches the colour and grain orientation of the wood under repair. [7] Patching wood requires skill, but when done properly it is possible to create a repair that is very difficult to see. An alternative to patching is filling (sometimes known as stopping).

   Wood glue is an adhesive used to tightly bond pieces of wood together. Many substances have been used as glues. Many substances have been used as glues. Traditionally animal proteins like casein from milk or collagen from animal hides and bones were boiled down to make early glues.

8. 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.

9. Wood–plastic composite - Wikipedia

   en.wikipedia.org/wiki/Wood–plastic_composite

   Wood-plastic composite. Wood–plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s) such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), or polylactic acid (PLA). In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials.
