Carbon Black N990
Part One: Description:
According to the specific surface area, thermal cracking carbon black is divided into Carbon BlackN800 or Carbon Black N900 series carbon black, and furnace carbon black is from Carbon Black N100 to Carbon Black N700 series. Thermal cracking carbon black has the largest particle size (average diameter 240-320NM) in carbon black, and its specific surface area is the lowest, only 7-11m2 / G. Relatively speaking, the particle size of furnace carbon black is three to twenty times smaller than that of thermal cracking carbon black (its average diameter is 15-80NM), and its specific surface area is 27-145m2 / G
Part Two: Application:
The compounded rubber blended with Carbon black N990 has the lowest viscosity, making the compound easier to process and easier to fill into complex molds. This is especially true for injection molding. The vulcanization time of the compounded rubber with N990 is t90, which is the longest time among several compounds, making the compound have better scorch safety. The most non-reinforcing carbon black, N990 carbon black is often mixed with other types of carbon black or mineral fillers to achieve more specific properties. Such as high tensile strength. Compounds mixed with N990 have low tear strength due to carbon black's lack of reinforcing effect on the molecular chain

Part Four: The advantage of Carbon Black N990
Thermal Cracking carbon black is the most commonly used as reinforcing filler in the rubber industry. Generally 90%-95% quality are widely used in the rubber industry.Its consumption is about 40%-50% the total rubber consumption.
1. Comparing with furnace carbon black, It can improve the filling amount in tyre texture industry.
2. Reduce the cost of rubber compound due to the high carbon black filling degree;
3. Keep the lower hardness and avoid the edge of inner tyre are from tearing.
4. Excellent resilience performance, low compression permanent deformation, low heat generation
Part Five: Package
