Kureha Extron developed Krefine Special Carbon Material made from petroleum pitch.
Krefine Special Carbon Material has the unique electrical property and less density than those of general carbon materials.
Krefine Special Carbon Material is able to control product’s surface resistance precisely, and to lighten product weight.
It have granular powder and sphere bead two shape;
Volume resistivity is 107Ω/sq;
Mean diameter of granular powder is 22um, mean diameter of sphere bead is 500um.
