Magnesiumhydroxid
Built for low-smoke zero-halogen compounds: decomposes endothermically above 300 °C, releases water vapour rather than toxic or corrosive gas, and is surface-treated so it disperses in polyolefins without overloading the formulation with coupling agent.

Sample Certificate of Analysis (example)
High purity magnesium hydroxide. High activity and high dispersibility let it compound into polymers easily, so it works as a functional filler and as a precursor to high purity MgO — where a hydroxide route disperses better in the process than a pre-calcined oxide.
Details anzeigenHigh purity magnesium hydroxide at 99% minimum, with acid insoluble matter held to 0,07% and chloride to 0,35%. Sits alongside ZH-H1 for electronic and functional materials; the two differ in impurity limits and bulk density, not in chemistry.
Details anzeigenHigh purity magnesium hydroxide, third step in the H series. Held at P1 deliberately: H1/H2/H3 differ too little to publish all three without thin content.
Details anzeigenIt is a vulcanising agent and a vulcanisation activator — not an accelerator and not a filler. MgO controls scorch time, raises crosslink density and neutralises the acidic by-products of vulcanisation. If you dose it as if it were a filler, the compound will not cure the way your formulation expects.
Bulk density. Light grades have low bulk density and high specific surface area — they react faster and occupy more volume per kilogram. Heavy grades are dense and free-flowing. Light is the conventional choice for rubber; heavy suits technical ceramics and volume-limited processes. A container of light material fills by volume long before it fills by mass, so quote by tonne and plan by cubic metre.
Active MgO has a high specific surface area — ZH-M600 runs at 175 m²/g minimum and ZH-V150 at 150 m²/g. Specify it when reactivity is what your formulation is short of: adsorbents for harmful gases, electronic components, inks, and rubber or plastics where it functions as both filler and reinforcing agent. If the constraint is purity rather than reactivity, ZH-V2 or ZH-V3H is the right choice instead.
