SPHERON® SO

SPHERON® SO by Cabot is a carbon black. It has high cleanliness and soft pellets for improved dispersion. It exhibits rubber reinforcement and processing properties similar to those of ASTM N550 carbon black and imparts fewer visible imperfections on the surfaces. It possesses longer screen life (fewer screen changes) and less wear on extruder barrel, screw and die from abrasion compared to conventional ASTM carbon black products. It is suitable for industrial rubber applications that require good extrusion characteristics and low hysteresis with more reinforcement than ASTM N700 and N600 type carbon black products. It is used in automotive weather stripping and door seals, extruded hoses and profiles and anti-vibration and other molded rubber parts. SPHERON® SO conforms to ASTM N550 carbon black target values.
