Poron is specifically made to have amazing performance absorbing shock from your feet. It protects car parts and computer parts as well. The way Poron was designed makes it very dense, helping it absorb energy when something is dropped.
Polyurethane foam does exist and is mostly widely used in Building and construction, Transportation and Appliances. More information about urethane foam can be found at wikipedia which has an whole article on it.
wHAT SIDE EFFECTS COULD BE EXPERIENCEd from using urethane foam padding?
The MSDS sheet for urethane foam suggests it's generally safe. The only hazard listed is minor respiratory problems from inhaling the dust.
He uses many materials, e.g. stainless steel, urethane foam, resin, urethane enamel, ...

First you have to make a mold. Then mix a two part foam into the mold. This will give you a copy made of foam. The cost for making a full size mold will be high.

Yes and no. It is very similar to urethane squirt foams like GreatStuff, and such, but it does not have any blowing agents in it. So it will not foam up to fill gaps. But it does bubble and expand a bit as it cures. Glued joints in wood will likely need to be scraped and sanded after the glue dries.

as a weighing agent in oil-and gas-well-drilling fluids to maintain pressure and prevent blowouts. It was also used as a weighing additive in cement, rubber, and urethane foam and for metal protection
Froth foam is a light, airy substance created by mixing air into a liquid, typically by whisking or frothing. It is commonly used in beverages like cappuccinos and lattes to add texture and a creamy consistency. Froth foam can also be created in cooking to incorporate air into ingredients for a lighter end result.
Main physical deficiencies during flexible foam production include uneven cell structure leading to inconsistency in foam properties, poor foam rise resulting in inadequate foam density, and improper foam curing causing variations in foam hardness. These deficiencies can impact the quality and performance of the final foam product.
