Product Details


Magnesium Hydroxide


Applications  Special for  Copper-clad Plate





1) Fine particle size, narrow particle size distribution, high whiteness degree, good physical and chemical properties, pure quality, high content, able to meet the requirement of base plate on high heat resisitance and low expansion factor;

2) Low hardness, small frictional loss on production equipments, good for later processing of copper-clad products, such as boring.

3) Little influence on mechanical property for application in laminated products, no flaking, no influence on the service life of products;

4) Products after activating treatment having good stability, excellent dispersibility and no agglomeration in resin system.


Product Information

Magnesium hydrate fire retardants reduce the surface temperature of the flame, in which the synthetic materials are packed, by releasing hydrate water and absorbing a large amount of latent heat. These functions are restraining polymers from composition is also a good fire retardant material and can help to improve the refractory property of the synthetic materials, while the emitted vapor can be used as a kind of restraining smoke agent.



Nowadays magnesium hydrate is generally considered as an excellent fire retardant in the field of rubber plastic industry for its triple function inflaming retarding, smoke restraining and packing. Its molecular formula is Mg (OH) 2 and the molecular weight is 58.32 . It is a kind of nontoxic, and high decomposition temperature. And it doesn’t corrode equipments. So it is the first selected material to be used as organic high-polymer for producing non-halogen ting inflaming retarding.

Company Profile

Dalian Yatai Science And Technology New Material Co., Ltd. is a stock company which produces professional Mg(OH)2 environment-friendly style fireproof and low-smoke halogen less fireproof materials. Our company has mines, a processing factory, research and development department and sales department. Our company has passed ISO9001 quality system authentication, and is the member unit of the council of plastic modified committee, wire and cable association and fire proof association.

Our company uses brucite which has high quality as raw material and cooperates with many universities and science research institutions to develop rubber-plastic halogen less fireproof products and produce professional Mg(OH)2 fireproof materials of fine quality & stable performance. Our products are suitable for wide plastic-rubber fields of PE\PP\PVC\ABS. As halogen less fireproof materials, our products comply with the development trend of environment protection in plastic industry and have bright market prospects. On the basis of the above mentioned products, our company has developed low-smoke halogen less fireproof cable materials, whose indexes all conform to or exceed the product level of the same industry in domestic market and reach international level. In the meantime, we have the production and activation ability of plastic accessory ingredients, such as super-fine Mg(OH)2.

Our company has had a group of experienced professionals engaged in management, science research and sales for several years. We hope that we can cooperate in good faith with trade people at home and abroad to develop much wider fields and create a great future together with reasonable price, the best reputation and the best service on the basis of mutual benefit.
