Table of Physical and Chemical Properties

Primary Particle Size Arithmetic mean diameter calculated by electron microscope.
Nitrogen Absorption Surface Area Specific area characteristics calculated by using low-temperature nitrogen absorption method (JIS K6217). Generally, the larger the value, the smaller the particle size.
Tinting Strength Carbon black is milled together in a Hoover Muller with zinc oxide to make a paste, the color of which is compared with a standard specimen (JIS K6217).
Oil Absorption Using and absorptmeter, the amount of DBP absorbed per 100g is measured when DBP is added to carbon black (JIS K6221)
The higher the structure, the higher the value.
Volatile Content Percent by weight which is reduced when carbon black is heated to 950°C for 7 minutes. The more the surface functional groups, the larger the value.
pH Value Value measured with glass electrode pH meter when carbon black is mixed with distilled water.
Ash Content Remaining percentage by weight when carbon black is burned at 750°C (JIS K6218).
Blackness of PVC Resin The respective blackness values of compounds after carbon black is milled with PVC resin.
