Melamine, a white, crystalline, slightly water-soluble solid, C3N3(NH2)3, used chiefly in organic synthesis and in the manufacture of resins, especially melamine resins.
Melamine is an industrial chemical, officials issued regulations banning the use of melamine in food products.
Product Specification and Packing Specification
a) Double-layer packaging: the outer packaging shall adopt type-B plastic woven bag specified in GB/T8946-2013, and inner packaging shall adopt polyethylene plastic film bag with the opening of film bag bound and the opening of woven bag sewn. The net weight of each bag is 25kg±0.1kg or 40kg±0.2kg.
b) Flexible container packaging: flexible container shall be adopted, and its specification, dimension, performance and inspection method shall conform to relevant provisions of GB/T10454. According to the user needs, the net weight of each bag can be 250kg±0.5kg, 500kg±1.0kg and 1000kg±2.0kg. Or it shall be packaged according to the users' requirements in the condition of meeting the safety requirements
Product Application
It can produce melamine resin with formaldehyde through condensation polymerization, be used in plastics and coating industry, and also be used as anti-crease and anti-shrink treatment agent for textiles. Its modified resin can be used as metal coating with bright color, high durability and good hardness. In addition, it can also be used for firm and heat-resisting decorative sheets, moisture-proof paper and gray leather tanning agents, the adhesives for composite fireproof laminates, fixing agents or hardening agents of waterproofing agents, etc. The 582 melamine resin made by melamine, formaldehyde and butanol can be used as the leveling agent of solvent-type polyurethane coating with good effect.

As a high opening ratio of three-dimensional mesh structure of the new type foam plastic,Melamine foam plastics' excellent properties in flame retardant,thermal stability,heat insulation,sound-absorbing and noise reduction,etc.,played an important role in energy saving and consumption reducing,which effectively enhanced the environment comfort of construction and improved the safety level of the building itself.As a new type of multi-purpose building material,Melamine foam plastics had broad prospect of application in the construction field.
Melamine formaldehyde foam is a new type of material,which has many good properties,such as fire-retardant,sound absorption and safety.Described the basic synthetic process of melamine-formaldehyde resin,and its foam preparation process.Introduced the domestic and abroad researches on modification of the melamine foam in detail.Described and forecasted the wide applications of melamine-formaldehyde foam in construction,fire-fighting and industrial fields.
