Grade:HGBD-1250
Product:Magnesium Hydroxide (Brucite Powder) HGBD-1250
Product Use:
Conveyor Belt (Rubber)
Simple rubber is a very flammable substance, therefore all rubber product formula must contain flame retardant. For instance, some neoprene rubber, when burnt, will release a large amount of hydrogen chloride gas, thus the fire will become more dangerous.
Constant friction and drive in a narrow space (resulting in the smoke being more dangerous), this greatly limits the relevant polymer for flame retardant material choice. In fact, the conveyor belt material must be included in the magnesium hydroxide flame retardant.
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.
