What is UFU urea formaldehyde foam insulation?

What does Uffi look like?
Visually UFFI looks like oozing liquid that has hardened. As UFFI ages it can darken and take on more of a butterscotch colour. New UFFI can often be a light yellow color. Early forms of UFFI tended to shrink significantly and the foam dried with a dull matte color. Very old cured UFFI can even be dry and crumbly.
