Magnesium hydroxide CAS 1309-42-8 MDH

Certificate of Analysis-COA 

Applications 

1.Halogen-Free Flame Retardant And Smoke Suppressant: Decomposing endothermically around 300-340°C, it releases water vapour that cools the polymer and dilutes flammable gases while a magnesia layer shields the surface, and it gives off no toxic halogen smoke.

2.Suited To High-Temperature Polymers: Its decomposition point sits above that of aluminium hydroxide, so it survives compounding in polypropylene, polyamide and other engineering plastics that are processed too hot for ATH-based flame retardant systems.

3.Wire, Cable And EVA Compounds: Used in halogen-free flame-retardant cable compounds based on EVA, PE and PVC, as well as automotive under-hood parts, EV battery casings, electronics housings and construction panels where low smoke emission is required.

4.Wastewater And Effluent Neutralisation: Dosed as powder or slurry to neutralise acidic effluent from metal finishing, mining and chemical plants, and to precipitate lead, copper, nickel and zinc into a denser, easier-to-dewater sludge.

5.Stable pH Control For Treatment Plants: Its low solubility delivers slow-release alkalinity instead of the sharp pH spikes caused by caustic soda, which supports biological treatment, curbs hydrogen sulfide odour in sewers and stabilises sludge in municipal works.
