Use

Melamine is a wide range of uses of the basic organic chemical intermediate products, the main purpose is the production of melamine-formaldehyde resin (MF) of raw materials. Melamine can also be made flame retardant, water-reducing agent, formaldehyde, etc. clean. Than the hardness of the resin of high urea-formaldehyde resin, non-flammable, water-resistance, heat resistance, aging resistance, arc resistance, chemical corrosion, good insulation performance, gloss and mechanical strength, widely used in wood, plastic, paint, paper, textile, leather, electrical, pharmaceutical and other industries.
