Versatile, high quality replacement in many Technical Rubber Goods applications
Rigorous testing revealed the true versatility of our revolutionary, green carbon black and its suitability for applications where mechanical and dynamic performance are of critical importance. Our grades act as a one-on-one, cost-efficient replacement for N330 and N660, providing comparable hardness with unique reinforcing characteristics and a PAH level below detection limits. We have also seen dramatic synergistic effects when blended with N330.
For Technical Rubber Goods, we manufacture two grades that prove a versatile, one-to-one replacement for a wide range of current grades;
BBC TR30 and BBC TR30S.

>> BBC TR30S
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

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.
The figure on the right provides a general substitution guideline for compounding with equal hardness.
