Cabot BLACK PEARLS® 2000 Specialty carbon black
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: General Description: BLACK PEARLS® 2000 carbon black is a very fine particle sized, super high surface area, conductive product with an extremely high structure. It is a furnace process carbon black designed for critical applications demanding excellent conductivity and good physical properties. BLACK PEARLS 2000 carbon black offers excellent conductivity and anti-static discharge properties at very low loadings in rubber compounds.

Performance Features: BLACK PEARLS 2000 carbon black has better electrical conductivity properties in rubber compounds than other Cabot conductive carbon blacks, VULCAN® XC-72, VULCAN® P and STERLING® C products. BLACK PEARLS 2000 carbon black is used in applications where other conductive carbon black products cannot meet the balance between conductivity and rubber property specifications. The percolation curve for BLACK PEARLS 2000 carbon black in rubber relative to other conductive carbon blacks can be found below. Rubber components having electrical resistivity in 103 to 106 ohm•cm range are normally classified as “antistatic” and components below 103 ohm•cm are classified as “conductive”. Rubber components made with BLACK PEARLS 2000 carbon black meet these conductivity requirements at relatively low carbon black loadings. BLACK PEARLS 2000 carbon black is also recommended for use in blends with other carbon blacks. The addition of a small percentage of BLACK PEARL 2000 carbon black can help to meet the required conductivity or anti-static level without the need for complex re-compounding without impacting other rubber properties. The rubber reinforcement properties of BLACK PEARLS 2000 carbon black are very high, well beyond the level offered by ASTM N100 and N200 type carbon blacks.

Typical Applications:

  • Antistatic and conductive applications
  • Hospital flooring and sheeting
  • Conveyor and power transmission belts
  • Hoses for mining, petroleum
  • Cable screening
