Magnesium Hydroxide

Applications  Special for  Copper-clad Plate

Advantages

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.

Properties

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.
