Features & Benefits

- Benefits
We have maximized the amount of silica in our BBC T30S to provide several differentiating benefits:
Improves tear strength and abrasion resistance
Receptive to silane-coupling for optimum mechanical/dynamic reinforcement
Reduces hysteresis and lowers rolling resistance
Enhances rubber-to-metal bond strength
Reduces electrical conductivity; especially valuable in applications where higher electrical resistivity is required

- User recommendations for substitution
The hardness/modulus contribution of carbon black grades are closely correlated to their structure (OAN number). Like the Black Bear grades, N326 and N660 are also low structure grades and therefore allow for a very close 1:1 substitution possibility.
Technical Details & Test Data
- Technical Positioning and Performance
BBC grades relative to competing ASTM rubber grades
Very low tan delta and Payne effect values combined with high mechanical reinforcement make the Black Bear grades extremely valuable in tires, and other demanding, dynamic applications where low hysteresis and low rolling resistance are key requirements.
The high surface area of the Black Bear grades combined with their relatively low structure provide high tensile strength, very high elongation, with relatively low modulus.
