MELAMINE
Applications Combined with formaldehyde to produce melamine resin. Its uses include
whiteboards, floor tiles, kitchenware, fire retardant fabrics, and commercial filters.
Can also be used in decorative and protective laminates used to manufacture furniture, flooring, and fiberboard.
Other uses include the production of particleboards, medium density fibreboards, surface coatings, enamels, paint additives, upholstery fabrics, flame-retardant clothing, heat resistant glove and aprons, and thermal liners.
Benefits Available in low pressure (Tsinghua) or high pressure (Eurotecnica) form Melamine contains 67% nitrogen by mass and, if mixed with resins, has fire
retardant properties due to its release of nitrogen gas when burned or charred. Melamine resin is a synthetic polymer that is fire resistant and heat tolerant. It
is a versatile material that has a highly stable structure. Can be easily molded while warm, but will set into a fixed form, which makes it
suitable for certain industrial applications.
