Carbon black N220

Carbon black N220 1. Iodine absorption:122 g/kg 2. DBP absorption:114 10-5m3/kg 3. Process: wet process 4. High quality

Carbon black N220

   Fine active carbon black. Imparts to rubber high wear resistance and tear strength, relatively low modulus.Mainly used in tyre tread, retreading. It aiso used in high-quality industrial rubber goods and high grade conveyor belts.

Characteristic: Good abrasion resistance and crack resistance. Its stress at definite elongation is lower. Application: Enhanced carbon black; Tire tread, high quality industrial rubber products and high load conveyor belt.
