Responding to diversifying needs for electric double layer capacitors

Medical/Environment-Related Environment-related Products

Functional activated carbon

Sales format
Granular, powdered, pellet, filter, fiber, sheet

Kuraray began production of activated carbon fiber (ACF) in 1980, and commercialized electric double layer capacitors that use ACF fabrics in the 1980s. Since then, we have commercialized fine powder activated carbon (YP, etc.) in response to the diversification of needs for electric double layer capacitors. In addition, we supply products to meet various other needs, including products for electrodes, water purification and deodorization.

Applications

Fine powder activated carbon

Electric double-layer capacitor (EDLC)

Characteristics

Fine powder activated carbon

Pores are highly controlled according to application.
Various forms are available from granularity to micrometer-scale powders.

Filters (molding carbon filters)

Broad adsorption performance due to approproate activated carbon composition.
Excellent characteristics and long life at high flow rate.
Appropriate as a preprocessing filter dur to minimal fine particle generation.

Activated carbon fiber

Pore size can be adjusted for a wide range of adsorptivity conditions.
Ideal permeability and good particulate removal.
Superb adsorption speed.

Activated carbon sheet

Level of activated carbon impregnation can be adjusted.
Ideal permeability and good particulate removal.

Impregnated activated carbon

Impregrated activated carbon has unique functions due to particular chemical treatment.
