Carbon Black
Carbon Black enhances the physical, electrical and optical properties of a wide range of materials; its largest use by volume is as a reinforcement agent and is key raw material contributing to the performance of rubber products. At Epsilon Carbon, we are using our vast experience in manufacturing coal tar derivatives to forward integrate to produce Hard and Soft Grades of Carbon Black that cater to tyre and non-tyre applications in domestic and international markets. Our Carbon Black grades exceed the global standards for Carbon Black set by ASTM, in addition, we can offer a range of Carbon Blacks that can be customised to specifications.
HARD GRADE CARBON BLACK
The hard grades of Carbon Black, also called ‘Tread Black’ is commonly used as the most cost-effective rubber reinforcing agent in tyre components such as treads.
We offer the following hard grades
N134
Has a very fine particle size, low micro-porosity and high surface activity, which makes it an excellent choice to provide great treadwear and tear resistance for tread compounds.
N220
Used in tread compounds of tyres for trucks and passenger cars, N220 grade offers high tensile strength. Its high abrasion properties make this grade the choice in rubber products such as high strength conveyor belts, industrial rubber articles, etc.
N234
An improved process high structure Carbon Black, N234 has excellent wear and extrusion properties. Used in all elastomers, especially SBR/BR blends for treads and tread rubbers.
N326
Used in mechanical goods, tyre carcasses, belts and off-road treads, due to its low structure, high reinforcement properties, high tensile strength and tear and chipping resistance.
N330
Provides good abrasion resistance, as well as high resilience, easy processing, good tensile strength and tear resistance. N330 is suited to a wide range of applications in both tyres and mechanical goods.
N339
Has excellent wear and extrusion properties characteristic of improved process high structure Carbon Blacks. It is suited to passenger treads, tread rubber, and mechanical goods.
N375
Mainly used in tread compounds of passenger, truck and cross-country tyres. It is also an excellent choice for the coating compounds of conveyor belts.
SOFT GRADE CARBON BLACK
Soft Grade Carbon Black or ‘Carcass Black’ is widely used in the sidewalls and inner liners of automobile tyres; other automobile parts such as sealing systems, hoses, anti-vibration parts; general rubber goods such as hoses, belts, gaskets, mats and seals.
When natural and synthetic elastomers are blended with Carbon Black, elemental sulphur, processing oils and various organic processing chemicals and then heated, they provide reinforcement and improve the resilience, tear strength, conductivity, etc., of a wide range of vulcanised rubber products.
We offer the following soft grades
N550
Imparts medium abrasion resistance, high tensile strength, low shrinkage and die swell. It also provides fast, smooth extrusions and relatively high resilience. It is used in tyre carcasses, cushion gums, tubing, cable jacketing, plastic conduit compounds, etc. It’s also used in extruded goods that require excellent dimensional stability.
N650
N650’s high structure and medium reinforcement gives low die swell and smooth extrusions, and allows easy processing and economic compounding. It is used in tyre carcasses, sidewalls, cable jackets, inner tubes and hoses.
N660
Is an excellent all-purpose Black, that can be used in tyre carcasses, sidewalls and mechanical goods. With moderately reinforcing properties, N660 provides good reinforcement, low heat generation, and smooth processing to all elastomers.
N762
A moderately reinforcing grade, N762 has excellent dynamic properties. It has high resilience, low hysteresis and allows high loadings. It is used in extruded goods, belts and hoses, moulded goods, and plastic colour concentrates.
N774
A moderately reinforcing grade, N774 has excellent dynamic properties. It has high resilience, low hysteresis and allows high loadings. It is used in extruded goods, belts and hoses, moulded goods, and plastic colour concentrates.
