Date : October. 10 2022|Announcer : admin

Melamine formaldehyde resin is also known as melamine resin, it is a polymer produced by the reaction of melamine and formaldehyde. Usually it and urea-formaldehyde resin is called as amino resin, melamine formaldehyde resin in the processing of a cross-linking reaction, so it is a kind of non-melting thermo– setting resin.

Firstly, the properties of melamine formaldehyde resin first small make up for you to briefly introduce its physical properties, cured melamine formaldehyde resin is colorless and transparent, it is extremely stable in boiling water, but also has self-extinguishing, good mechanical properties and arc resistance. Melamine formaldehyde resin is made of melamine and 37% formaldehyde aqueous solution reaction, because the reaction conditions are different, so the amount of molecules produced is different, its products have from water soluble to insoluble in water, and then to insoluble solid are not melting.

Secondly, the use of melamine formaldehyde resin
Melamine formaldehyde resin has played a huge role in many aspects: it can be used in the leather industry, it can be used as a pre-tanning, retanning and haniwa resin, it can also be used in the paper industry, mainly as a wet reinforcement and water resistance agent; In the coating industry is mainly used as waterborne coating crosslinking agent, can be widely used in household appliances, automobile and other industries: in the mold and plastic industry, its flame retardant, high temperature resistance, pollution resistance, safety and health advantages make it can be widely used in electrical parts, tableware, daily necessities and so on; In addition, it can also be used as ceramic and cement dispersant, wood binder, textile finishing agent, wastewater treatment flocculant and so on.

Thirdly, melamine formaldehyde resin consumer market
In China, the consumption market of melamine formaldehyde resin is mainly used in wood processing industry, which can account for 56% of the total consumption. The other consumption is mainly used in dry coating, molding board, leather manufacturing, textile industry and paper making and other industries. About 50% of melamine in China is mainly used for export. The largest domestic demand is in Guangdong, Guangxi, southern Jiangsu and other regions, with an annual demand of about 12,500 tons.
