Melamine-formaldehyde molding compound (commonly known as melamine powder), by formaldehyde and melamine condensation resin and a variety of additives compounded into a thermosetting plastic, belongs to the amino molding plastic, with easy to form, low shrinkage, high dimensional accuracy, good processing performance and other Chemicalbook advantages. Its products have excellent heat resistance, flame retardant and good mechanical strength. This material can be widely used in articles closely related to daily life. In 1938, CIBA of Switzerland successfully developed melamine formaldehyde resin, which became the beginning of its industrial production.

The condensation of melamine formaldehyde resin is carried out in stages. The first step is the addition reaction of formaldehyde and active hydrogen atoms of melamine amino to form the derivative of melamine hydroxymethyl (namely the initial product of resin). Then the formation of melamine hydroxymethyl derivatives to gradually condensation, the formation of various degrees of resin, and then in the high temperature further reaction, the formation of a body with insoluble insoluble properties of three-dimensional structure network structure thermosetting material. Chemicalbooka. A methylol melamine product form 1 mole of melamine and formaldehyde in 2 ~ 3 mole of medium for neutral or weak alkaline (pH = 7 ~ 9) under the condition of the heating formaldehyde and melamine amino active hydrogen addition reaction, the double bond of open and melamine formaldehyde amino active hydrogen and nitrogen atoms are linked together, can form a methylol melamine, melamine dihydroxy methyl and hydroxymethyl three melamine.
