Cabot Corp. has launched a series of low polycyclic aromatic hydrocarbon carbon black products for rubber product applications.
The Cabot LP carbon black series is engineered to meet customers' requirements for end-use product performance while reducing the PAH concentration to help customers comply with new regulations and quality certifications, Cabot said. The Cabot LP carbon black series is designed to provide customers with alternative reinforcing and semi-reinforcing carbon blacks for use in applications that require lower PAH content, the company said.
Cabot showcased the new series at the Deutsche Kautschuk-Tagung (DKT) show in Nuernberg, Germany, June 29-July 2.
The Cabot LP low PAH carbon black series features three products manufactured via Cabot's quality control process, yielding a consistent, very low level of PAHs, the company said. Additionally, the company claimed that series consists of one reinforcing and two semi-reinforcing carbon blacks, all of which are characterized by a controlled, very low PAH content:
• Spheron SO-LP carbon black: a semi-reinforcing carbon black with very high structure that is easy to disperse and provides excellent extrusion properties to rubber compounds. This is recommended for rubber compounds that require a very low PAH content and are based on standard ASTM N650, N683, N539 and N550 carbon blacks.
• Spheron 4000-LP carbon black: a semi-reinforcing carbon black with very low surface area and structure that offers excellent rubber compound flowability by imparting low viscosity even at high loadings. Spheron 4000-LP carbon black can replace ASTM N762, N772 and N774 carbon blacks in very low PAH content applications.
• Vulcan 6-LP carbon black: a reinforcing carbon black recommended for rubber products that require a very low PAH and higher reinforcement, strength, abrasion and tearing resistance level than offered by semi-reinforcing carbon blacks. VulcanCAN 6-LP carbon black is recommended for rubber compounds that require a very low PAH content and are based on standard ASTM N220 carbon black.
