Formaldehyde is also used as a denaturing agent in RNA gel electrophoresis, preventing RNA from forming secondary structures. A solution of 4% 

A copolymer containing melamine, formaldehyde, and sodium bisulfite produces a foam with sound-absorbing and flame-retardant properties. The foam has a notably hard microbubble structure, which gives it an abrasive quality that has been utilized in the development of cleaning products.

Formaldehyde (H2CO) is the simpiliest of a class of functional groups call Chain products are formed by further addition and condensation with the liberation of water and a mass molecule of phenol formaldehyde resin will form whose structure is shown in Fig. 30. The ratio of phenol to formaldehyde to form a mass molecule as shown in Fig. 30 is 1:1.5. Melamine was chemically introduced into a urea–formaldehyde system via co-condensation reactions during curing and foaming process, and a novel elastic urea–melamine–formaldehyde (UMF) foam with improved thermal stability, insulation property, and flame retardancy was fabricated. It was found that with a decrease of the mass ratio of urea formaldehyde resin and melamine formaldehyde I quickly take you through how to draw the Lewis Structure of CH2O (methanal or formaldehyde).
