Magnesium Hydroxide

Applications  Special for Rubber Hoses

Advantages

1) It meets the environmental requirements of ROHS directive of the EU. It is halogen-free, environmnet-friendly, and nontoxic. It is white powder and can be substitute for antimony trioxide. It's fire retardant and somke-suooressing.

2) The mechanical properties of the product are ensured to rech the standards. The product has been through the continuous activating modification process, which contributes to its better dispersal in the rubber hoses and belts.

3) It cooperates well with the bromine fire retardant. According to the requirements forfire retardant from the clients, 30%-50% of antimony trioxide could be substituted.

4) It is more competitive in price. When used as filler, the amount could be controlled on the basis of resin system and requirements of products property.

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.
