While providing various conductive and antistatic materials, we are also a supplier of acetylene carbon black. Acetylene carbon black is also known as highly conductive acetylene carbon black, extremely conductive carbon black and compression ratio carbon black. It is a carbon black with a purity of more than 99% obtained by decomposing and refining the by-product gas during the pyrolysis of calcium carbide or naphtha, and after continuous pyrolysis.

Our compressed carbon black is divided into 50% compression ratio, 75% compression ratio, 100% compression ratio, no compression ratio, N220, N326, N330, N550, N660, etc. There are other models that can be matched according to customer needs.

Acetylene carbon is black ultra-fine powder with a relative density of 1.95 (nitrogen replacement method). Apparent density 0.2~0.3g./cm3. The average particle size is 30~45nm°, and the specific surface area is 55~70m2/g. The iodine absorption value is 60~80gl2/kg. Yikuai carbon black is very high in purity, with a carbon content of more than 99.5%, a hydrogen content of less than 0.1%, and an oxygen content of 0.07% to 0.26%. pH 5 to 7. The resistivity is extremely low, and it has excellent electrical conductivity, thermal conductivity and antistatic effect.

As the anode material of radium dry battery, the carbon black is used together with bisulfite and electrolyte, and the crystal and bismuth are more developed, so the conductivity and liquid absorption are also better. Due to less impurities such as heavy metals, the loss caused by self-discharge is small, and the storage performance is also better. In addition, acetylene carbon black is also used in conductive, antistatic and thermally conductive rubber products, conductive coatings, and plastic products.
