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.
