25kg woven bag with plastic liner.

It can be used in intumescent fireproof coatings and thermoset resins, such as polyurethane, UP resin and epoxy resin. It can also be used in the retardant of fiber, wood ,rubber and plastic products. Due to its high molecular weight(n>1000) and good heat stability, APP can be used as main ingredient of expanding retardant thermoplastic.,especially used in the PP achieving UL94-V0 for electronic unit.

Physical feature: there are mainly 4 sizes of aluminum hydroxide, 325, 2000 and 3000 mesh.

Note :
(1) AL2O3 content is of the difference of 100% minus firing loss and impurity content.
(2) The chemical composition is calculated of the baking at 110¡À5¡ãC for 2 hour.
(3) The impurity content is treated in line with the number rule of GB8170.

2.Application:
Aluminum hydroxide is the most consumable and applicable inorganic additive flame retardant that does not only resist firing, but also prevents from smoke, dropping or toxic gas. So, it is widely used with gradual increase of the usage, at the sectors of hot solidifying and moulding plastic, synthetic rubber, coating and construction materials.
