Himadri’s KLAREX carbon blacks were developed to meet the demanding requirements of the extrusion market such as weather stripping, automotive door seals, extruded hoses and profiles, and complex moulded rubber parts. It offers very low grit producing parts with superior smoothness and good compression set. The low grit improves processability and reduces defects and scrap rates. The cleanliness and quality of KLAREX carbon blacks are achieved by tight feedstock control, proprietary process technology, and stricter manufacturing controls as compared to ASTM blacks.
