Higher processing temperature
Stable to about 330 ℃, so it suits PP and polyamides.
水酸化マグネシウム (MDH) is a halogen-free mineral flame retardant and smoke suppressant for polymers processed at higher temperatures, such as polypropylene, polyamides and cable compounds. SUNCHEM supplies magnesium hydroxide with a batch COA on every shipment; the TDS is sent on request.
Magnesium hydroxide decomposes at about 330 ℃, absorbing heat and releasing water vapor, which cools the polymer and dilutes the flame; the magnesium oxide residue reduces smoke. Its higher decomposition temperature than ATH lets it be compounded into polypropylene, polyamides and other polymers processed above 200 ℃.
As a high-loading filler, 粒子サイズ, purity and surface treatment decide melt flow and mechanical properties.
Stable to about 330 ℃, so it suits PP and polyamides.
Releases water and reduces smoke, with no halogen.
We quote against your Mg(おお)₂ content, 粒子サイズ, 白さ, CaO and Fe content, moisture and surface treatment and send the batch COA for each lot.
