SPHERON® 4700

SPHERON® 4700 by Cabot is a carbon black. It is manufactured via a special process, resulting in a very low amount of impurities such as grit, process water salts and metallic particles. This grade is similar to the SPHERON® A grade family and offers low level of impurities. It exhibits rubber reinforcement, surface area, structure values and compound processing properties comparable to ASTM N772 series type carbon black. It contains a very low amount of +120 Mesh size impurities and imparts a reduced number of visible imperfections, thereby offering better surface finish than ASTM N772 carbon black. SPHERON® 4700 is used in wide range of industrial rubber product applications such as extruded profiles and injection or compression molded rubber seals and automotive door seals.
