3. Application

(1) The product has been used as filler to produce artificial marble (DuPont stone) for its low viscosity in resins and quick hardening at room temperature.

(2) The product has been used in polyvinyl chloride, epoxy resin, polyester resin, polyurethane resin, PE, EVA, rubber, silicone rubber, electrical and electronic products as fire-retarding filler, especially surface-coating powder offer better compatibility with resins, the properties of resultant articles display better mechanical, flame retarding and smoke inhibiting properties.

(3) The product has been used in preparing toothpaste as an excellent frictional agent for high- and middle-class toothpaste duo to its moderate hardness and good taste.

(4) The product has been applied in water-proof fabric, ink, glass, filler of paper, mordant, water-purifying agents, also used for preparing aluminum based compounds and lubricants.

 

As a new inorganic fire retardant,it has the features of non-halide,low smoke ,non-tonix,anti-drop and filling.
