New aluminum hydroxide

Development of new varieties, including:
(1) increasing the surface area of ??the aluminium hydroxide particles and ultra fine micronized, water vapor partial pressure of the particle surface decreased, aluminum hydroxide can be improved heat resistance and mechanical properties of the material, significantly enhanced flame-retardant effect, tests showed that the same Recipe average particle case of aluminum hydroxide

Diameter of 5μm, the oxygen index of 28, particle size <1μm, the oxygen index of 33.
(2) thermal decomposition of aluminum hydroxide and the reaction temperature of the material, can be synthesized in between the thermal decomposition temperature of new varieties, such as aluminum hydroxide and sodium carbonate eutectic at 300 ~ 350 ℃ decomposition discharge water and carbon dioxide, hydrogen chloride and smoke have a stronger inhibitory effect is

PVC, polyolefins excellent flame retardant.
(3) reducing the insoluble aluminum hydroxide ions especially sodium oxide content, the mass fraction of less than 0.2%.
