zirconium phosphate CAS NO.13772-29-7

White powder, with 1.66g/cm³ of density, same common property of layer compound, high stability with its chemical property and layer structure, relative bigger proportion of surface percentage ( total area of the item), high electric density on its surface(charge numbers on its surface per unit), is a strong type of solid acid. It’s insoluble in water and an organic solvent with resistance to strong acid and certain soda. It has high stability and intensive mechanical strength. (When this material encounters with external force, the unit area can bear the highest capacity

MCA-a-ZrP was synthesized by self-assembly of ME and CA on the surface of a-ZrP powder. Compared with pure PA6, Ti of PA6/MCA and PA6/MCA-a-ZrP composites increased. The HDT values of PA6/MCA-alpha-ZrP with different content of alpha-ZrP were significantly higher than those of pure PA6 and PA6/MCA composites. UL-94 results showed that the flame retardancy of MCA was enhanced to V-2 grade, while that of MCA modified by alpha-ZrP was enhanced to V-0 grade, and the residual carbon content was higher after combustion. Adding enough alpha-ZrP (30wt% MCA) increases the crystallinity of PA6 and tends to form gamma phase. These results indicate that alpha-ZrP and MCA have significant synergistic effects on improving the flame retardancy and crystallinity of PA6, while maintaining excellent mechanical properties.
