Detailed Product Description

Grade:HGBD-2500

Product:Magnesium Hydroxide (Brucite Powder) HGBD-2500

Product Use:

Polyolefin Compound (HFFR)

Polyolefin compounds are gradually replaced by PVC compounds and has been widely used in smoke and gas emission demanding areas, especially in the underground pipeline, public places and insulated wire cable and so on. These materials are processing temperatures of up to 300 ℃, so that a lot of polyolefin productions are based on the magnesium hydroxide flame retardant agent to produce compact final product.

Brucite is widely applied in different fields, such as steel slag, power plants flue gas desulfurization, magnesia fertilizer, waste water treatment and so on.
But the most important factor in the application of magnesium hydroxide flame retardant is that all polymer composition must comply with strict fire safety and smoke and poisonous gas release requirements. However, the use of natural brucite production of magnesium hydroxide flame retardant products meet all the requirements.

Decriptions

Magnesium hydroxide(Brucite Powder) is a physical flame retardant with three functions of flame retardant, smoke limited and filling in rubber and plastics. It has the characteristics of non-toxic, odorless, good stability, non-volatile, well dispersion, non-corrosive, etc. And it is the preferred option of filler material for polymer material with effective flame retardant.

Magnesium hydroxide(Brucite Powder) flame retardant releases water when it is thermally decomposed, absorbs a large amount of latent heat to reduce the surface temperature of the synthetic polymer material with filling brucite powder , and has the functions of inhibiting polymer decomposition,meanwhile cooling the generated flammable gas. The decomposed magnesium oxide is also a good flame retardant material, which can help improve the fire resistance of synthetic polymer materials, and the water vapor it releases can also be used as a smoke limited.

Application

Magnesium hydroxide(Brucite Powder) is widely applied in different fields, such as steel slag, power plants flue gas desulfurization, magnesia fertilizer, waste water treatment and so on. The detail application as following:Polyolefin Compound (HFFR),Wire Electric Cable(PVC),Crosslinked Polyethylene (XLPE),Polypropylene(PP),Conveyor Belt (Rubber),Silica Gel,Electrical Parts (PA),Floorboard,Wallboard,Stack desulfurization.

Advantages

a. halogen-free, easy to disperse and good compatibility.
b. Excellent Stability and products meets clients requirement absolutely
c. Excellent performance on physical properties and flame retardant.
d. Good heat stability, decomposition temperature at 330 ℃, especially suitable for resin processed in relative high temperature.
