UF (Urea Formaldehyde)
Solidity, being warm to the touch and high density are the characteristics that summarize the properties of urea formaldehyde. A nitrogen-rich waste product of urine, which, to produce a plastic compound, is condensed with formaldehyde. Part of this process yields a water-soluble liquid, which is used in adhesives and coatings, particularly in making pressed wood products such as medium-density fibreboard (MDF). The final part of the process yields a water- and chemical resistant resin for plastic moulding.
