Carbon Black N234

Other Name: Intermediate Super Abrasion Furnace Black-high structure（New technology）；ISAF-HS（New technology）

ꄴPrevious： CARBON BLACK N660

ꄲNext： CARBON BLACK N326

Physical & Chemical Properties: Carbon black N234, compared to other grades of N220 series, has higher structure, higher abrasion. Its iodine adsorption value is 120g/kg, and DBP adsorption is 125cm3/100g.

Application: Carbon black N234 is used in the tread compounds of high speed tire and high performance rubber products.
