Acetylene black
is produced with high pure acetylene, which made from calcium carbide method,
Acetylene carbon black is made by the controlled combustion of acetylene in air under pressure.
It is characterized by the highest degree of aggregation and crystallization orientation when compared with all types of carbon black.
It has high iodine absorption, effective conductivity and steady chemical performance. It is not easy to react with acid, alkali and water and is an excellent raw material for battery, conductive rubber, plastic, cable, etc.
