1. Specifications

N220/N330/N550/N660

CAS RN. 1333-86-4
EINECS NO. 215-609-9
Molecular formula: C
Molecular weight: 12.01
Materialization properties: Water soluble Insoluble

1). The ratio of nitrogen-adsorption on the carbon black surface is recommendatory test index.

2). 300% Stretching Stress is to get the carbon black disparity between the everyday carbon black (SRB3#) sample and the standard in the same experimental situation, with I type and dumbbell type reamer set by GB/T528. The vulcanization of the carbon black lasts 30 minutes under the average temperature of (145±1) .

3). All the technical indicators are taken as that of qualified products.

3.Applacation:
Mainly used for tungsten carbide as raw material carbonization , also can be used for carbonization , electronic , fine ceramics and raw materials for solar-grade silicon ,metallurgical reductant.

4.Packaging:
20kg knitting bags top grade liner film, good properties of waterproof and avoid water, solarization.13MT/1x20ft 26MT/1x40ft
