Usage:
Melamine is a constant presence in everyday life. Dinnerware, laminates, flooring, medium density fibreboards, owe their hardness, flame-resistance, mar-resistance and waterproofing to melamine. Being able to form strong stable bonds with formaldehyde, melamine confers MF and MUF resins unique features thanks to the high nitrogen content (66% wt) of the molecule, which is essential for the flame-retardant and fire-resistant properties in the finished goods. If exposed to intense heat they give off nitrogen without toxic gases, diluting oxygen and inhibiting the combustion. New aircrafts interiors, for instance, make use of melamine-based flame-retardants in order to comply with the most stringent safety requirements.
M
elamine is mainly used for manufacturing melamine formaldehyde resin, which is well water, heat and arc resistant and bright. It can also be used in decorative laminates, amino plastics, adhesive agents, coatings and used as a paper reinforcing agent, textile auxiliaries, cement water-reducing agent and leather retaining agent etc.
