Higher processing temperature
Stable to about 330 ℃, so it suits PP and polyamides.
MDH
수산화마그네슘 (MDH) Supplier from China
수산화마그네슘 (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.

제품개요 & 주요 이점
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, 입자 크기, purity and surface treatment decide melt flow and mechanical properties.
Low smoke, 할로겐 프리
Releases water and reduces smoke, with no halogen.
Specified on your terms
We quote against your Mg(오)₂ content, 입자 크기, 흼, CaO and Fe content, moisture and surface treatment and send the batch COA for each lot.
