氢氧化镁具有阻燃性能

Magnesium Hydroxide 1.brief introduction In order to produce fire retardant Magnesium Hydroxide,it must be fine crystal shape, small average partical size,small specific surface area, prone to decentralize,hard to reunite and surface polarity eliminated.Adopt synthesized techniques onMagnesium chloride as raw material,treat Magnesium Hydroxide with hot water,and then make it as fire retardant which can be used in plastic and rubber through surface treatment to have the characteristic of low initial decompose temperature and 10% more heat absorptivity compared with aluminium hydroxide.It can be applied in PE,PVC,PP and also in PET,PBT,PA,PPO,and ABS ans so on. 2.Index index FR-HFR-SMH-01MG-02Mg(OH)2≥% 99 96 95 Brightness≥ 95 90 92 Acid insoluble matter≤% 0.05 1.5 2.3 Iron(mesured in Fe) ≤% 0.05 0.25 0.25 Chlorine(measured in Cl) ≤% 0.3 0.4 0.4 Free water≤% 0.5 0.3 0.3 Average particle size(um) 1.2-3 4-8 3-10 Remarks: 1.provide surface appearance according to customers 2.accorde wit EU ROHS 3.packing 20 kgs or 25 kgs/ pp woven bag or just as customers requirement
