Flame Retardant - Magnesium Hydroxide

Non Halogenated FLAME RETARDANT
(Magnesium Hydroxide)
SWISS MAG
Appearance: White powder
SwissMag is able to take over in the higher temperatures where Aluminium Trihydrate (ATH) leaves off. While functioning in the exact same manner as ATH, there is one key difference: SwissMag undergoes endothermic decomposition when water is released at 340° Celsius or 626° Fahrenheit. That means it is thermally stable at temperatures up to 120°C higher than ATH.
When heated to 340°C, it will decompose into MgO, and produce plenty of hydrosphere. MgO is a high temperature resistant material, and that water can prevent flame spreading, this is flame-retardant mechanism of SwissMag. At present, halogen flame retardant is still used in many fields, although it can release the poisonous gas, causes “second disaster” as fire occurs. Inorganic hydroxide flame retardant agent decomposes plenty of hydrosphere and absorbs lots of heat energy when it is burning, and forms a “ceramic slipcover” on the burning object. Smoke, poisonous gas and corrosive gas, and then be absorbed; it can solve “second disaster” effectively. The temperature span of the hydroxylation of SwissMag is small, which makes hydrosphere release easily and has perfect fire retardant effect. SwissMag flame retardant agent is becoming more and more popular with ideal flame-retardant, curb-smoke and filling effect.
Compared with traditional flame-retardant agent, i.e. Aluminum Hydroxide and halogen product, Swiss MS has the following characteristics:
● The decomposing temperature is well situated (start decomposing at 340℃), for the smelting and extrusion of plastic；
● Environment-friendly product, high temperature decomposing, no gas letting-out, low-smoke, curb-smoke；
● Reduce the cost of plastic products；
