1. Wet type Aluminum Hydroxide(ATH)

• This is 3 molecules crystalline ATH that contains free-moisture. It is easily dissolved in response to acid and alkali.

2. Dry / Fine ATH

• product is produced by removing only free-moisture from the surface of Wet type ATH. The reactivity and solubility to acid and alkali are the same as Wet type ATH, but easy to handle and to mix other additives.

• It is low viscosity so that it is used as a filler.

• It is thermally stable upto 200°C so that it is used as a flame retardant material for rubber and plastic.

• flame retardant, it emits only water molecules as the temperature rises, so there is no toxic gas or smoke. It has excellent tracking resistivity, so it is widely used as an electrical insulating material.

3. Super Fine ATH

• Excellent whiteness, Low conductivity and Low absorption rate

• When used as a flame retardant, it emits only water molecules as the temperature rises, so there is no toxic gas or smoke. It has excellent tracking resistivity, so it is widely used as an electrical insulating material.

4. Boehmite

• It is used as an environmentally friendly halogen-free flame retardant

• No toxic gases or fumes are generated in high temperatures or flames, and it has excellent tracking resistivity.

• It can be applied to PCB.

1. Calcined Alumina

• As a hexagonal crystalline structure, it is most commonly used for flame retardants, ceramics, and abrasives, etc.

• It contains very low amount of micro particle. An average particle size is 3~5um.

2. Low-Soda Alumina

• This is the crystallized α-Alumina calcined in a rotary kiln at high temperature.

• Soda content is below 0.05% and α-size is 1~4um. It is mainly used for Alumina ceramics, ignition plug and electronic insulation products.

3. Super Fine Functional Alumina

• This product stands for Super fine alumina and easily sintered alumina. The raw materials are calcined alumina for sintering and low caustic soda alumina. After the milling process, it is classified into three Grades: low, medium and normal caustic soda content.

• They are widely used for alumina ceramics in the electro-ceramics industry because of its characteristics of heat-resistance, chemical stability, high strength, abrasion-resistance, electro-insulation, etc.
