Carbon Black / N650
N650 is a medium-dispersion, medium-active, low-structure carbon black, used for industrial rubber goods. It provides higher die-swell and high resilience at relatively high hardness. N650 may be incorporated in large quantities and can be used as compounds for tire carcasses and tubes. Used for moulded goods, goods extrusion, industrial rubber products, sleeves, one-layer roofing systems and isolating cable rubbers.
