Because it is formed by chemical reactions with formaldehyde is can be an environmental hazard and there is particular concern regarding indoor air quality. Virtually all modern houses and buildings will have some material made with urea formaldehyde. The problem occurs when the chemical reactions involved in manufacture do not completely use the formaldehyde chemical. This has been a serious problem in the past when production processes were shoddy. It is part of the air quality standards of the US Environmental protection Agency.
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde

Phenolic resins are made from chemicals of the phenol group while urea formaldehyde resin are made from urea and formaldehyde. These two resins have different properties.
Paraformaldehyde is a solid form of formaldehyde. ithas the same uses as formaldehyde. Like Formaldehyde, Paraformaldehyde also reacts with phenol, urea, melamine or resorcinol and produce resins used as binders. Regards Sharad Madhukar Koparkar India
It is poisonous
The laboratory preparation of urea-formaldehyde with melamine formaldehyde resin added is meant to modify the urea-formaldehyde resins in order to get good performance with a low formaldehyde emission. The optimal percentage of the melamine resin is 20 percent of the entire solution.
Thermosetting
this is the poly-condensation reaction of urea and formaldehyde at acidic medium ..this is milky type productive used as adhesive in plywood industry.
Curlinterrupted contains Urea which is a releaser of Formaldehyde. The longer the ingredient stays in the bottle the higher the levels of Formaldehyde.
