The poisson ration of uncompressed polyurethane is 0.5; the poisson ration of polyurethane under compression is 0.39. Reference: "Material behaviour in plane Polyurethane - Polyurethane impact with velocities from 10 to 400 m/sec." Published at J. Phys IV France 7 (1997)
Polyurethane will give a long lasting easy to apply finish. Use a water based polyurethane ans clean up will be much easier. You should get years of wear from a good polyurethane finish.

Polyurethane is an extra-tough material found in paints which also has excellent electrical insulating properties.

You need to define the answer. Foam can be confused with bubblly foam (like in the bath, doing the dishes) and then there is Polyurethane foam, what people use as padding for insulation. For Polyurethane foam information, seek out this information from this eHow website: http://www.ehow.com/about_4673650_history-polyurethane-foam.html
He invented the process for making the multipurpose material polyurethane. He was helped by Donald Fletcher Holmes.
Polyurethane can be recycled.
Yes, polyurethane is paintable.

Yes, water-based polyurethane can be applied over oil-based polyurethane after proper preparation and sanding.
Yes, you can apply polyurethane over old polyurethane when refinishing furniture. It is important to properly prepare the surface by sanding and cleaning it before applying the new coat of polyurethane for best results.
No, it is not recommended to apply oil-based polyurethane over water-based polyurethane as they are not compatible and may not adhere properly. It is best to stick with the same type of polyurethane for a consistent and durable finish.

Yes, polyurethane is typically oil-based.
The most effective method for removing polyurethane using a polyurethane remover is to apply the remover to the surface, let it sit for the recommended time, and then scrape off the softened polyurethane using a scraper or putty knife.
