Grade:HGBD-2500
Product:Magnesium Hydroxide (Brucite Powder) HGBD-2500
Product Use:
Wallboard
Wallboards have a vertical characteristic, it is easy to create vertical combustion and plus the matrix is polyethylene polymer. Therefore, there is more a need to adopt magnesium hydroxide flame retardant. By doing so, will achieve better efficiency and easier to process products. Also, requirements for no surface treatment of magnesium hydroxide flame retardant is low cost thus making it a good incentive.
