ASTM Blacks
Himadri’s ASTM carbon blacks are produced to the exacting standards to ensure lot-to-lot consistency.
Himadri produces both tread (reinforcing) and carcass (semi-reinforcing) carbon blacks primarily
used in tyres and mechanical rubber goods (MRG).
Reinforcing (Tread) Carbon Blacks
| ASTM Grade Black | PRODUCT DESCRIPTION | EXAMPLE APPLICATIONS | Technical Data Sheets |
|---|---|---|---|
| N115 | High surface area at relatively low structure proving high degree of reinforcement providing high tensile and rupture strength as well as cut & chip resistance | • Off-road tires • Truck tires • MRG products requiring high wear resistance and tensile strength |

| N121 | High surface area and structure provding high tread wear resistance | • Tire tread for all passenger, truck, and bus tires | SDS TDSGet a Quote |
| N134 | High surface area and structure provding high tread wear resistance | • Premium tire tread compounds for passenger, truck, or bus tires | SDS TDSGet a Quote |
| N220 | High surface area and medium structure enabling good extrudability in compounds while still proving high tensile strength and wear resistance | • Tire tread for passenger and Truck tires • Conveyor belts and other rubber products requiring wear and tear resistance |
