What category is urea formaldehyde?
nontransparent thermosetting resin
Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, is a nontransparent thermosetting resin or polymer.
Is urea formaldehyde and formaldehyde the same?
Formaldehyde is a colourless, strong smelling gas. It is widely used in the manufacture of building materials and numerous household products. There are two types of formaldehyde resin; urea formaldehyde (UF) and phenol formaldehyde (PF).

What is urea formaldehyde commonly used for?
Urea-formaldehyde resins are used mostly as adhesives for the bonding of plywood, particleboard, and other structured wood products.
What is the combination of urea and formaldehyde?
The combination of the urea and the formaldehyde gives both branched and linear polymers as well as the three-dimensional matrix that can be found in the cured resin. These different structures are due to the functionality of the urea and the formaldehyde.
When treated with phenol urea or melamine formaldehyde?
When treated with phenol, urea, or melamine, formaldehyde produces, respectively, hard thermoset phenol formaldehyde resin, urea formaldehyde resin, and melamine resin. These polymers are common permanent adhesives used in plywood and carpeting.
What compounds are not compatible with formaldehyde?
Incompatible with amines, azo compounds, dithiocarbamates, alkali and alkaline earth metals, nitrides, nitro compounds, unsaturated aliphatics and sulfides, organic peroxides, oxidizing agents, and reducing agents. Aqueous solutions are unstable. Commercial formaldehyde-alcohol solutions are stable.
Are Embalmers and anatomists at risk for formaldehyde exposure?
Several NCI surveys of professionals who are potentially exposed to formaldehyde in their work, such as anatomists and embalmers, have suggested that these individuals are at an increased risk of leukemia and brain cancer compared with the general population.
