Thermax N990 Thermal Carbon Black in Nitrile Rubber Compounds

The majority of rubber grade thermal and furnace carbon blacks are classified using a four-character naming convention as described by the ASTM standard D1765 The first character is a letter that indicates the effect of the carbon black on the compound cure rate in the case of N990 the (N) indicates a normal cure rate The next character is a number based on the average particle size of the
