Impervious graphite (RESBON®)

Impervious graphite RESBON ® is a superior corrosion-resistant material that is produced by the impregnation of resins into artificial graphite. Since the product first went on sale in 1949, we have delivered more than 6000 shells for tube-type heat exchangers and achieved a high evaluation. We also design and manufacture corrosion-resistant facilities.

Carbon Microbeads (NICABEADS®)

NICABEADS® (ICB, PC, MC-grade) are surface-coated micro bead-shape material produced by carbonizing thermosetting resin in our company's unique process. NICABEADS® MPA-grade is artificial graphite powder produced by pulverizing the pitch and then baking and graphitizing them. The product excels in dispersability, electrical conductivity and chemical erosion resistance, which enables it to be applied for conductive and sliding fillers.

Properties

NICABEADS® has three grades ; ICB grade with flat and smooth surfaces, PC grade with pitch based graphite coating on ICB grade and MC grade coated with carbon black on ICB grade. In addition, there's NICABEADS® MPA grade that has a clumpy form.
