SPHERON® 4700 by Cabot is a carbon black pigment (in the class known as Semi-Reinforcing Furnace (SRF) carbon blacks). 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. 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 impart a reduced number of visible imperfections, thereby offering better surface finish than ASTM N772 carbon black. Used in wide range of industrial rubber product applications such as extruded profiles and injection or compression molded rubber seals and automotive door seals.
