The ultra pure carbon black series uses natural gas as the raw materials, burns without flame under isolated air conditions, and is cracked to produce and also called 

thermal cracking method carbon black. Ultra pure carbon black series products are widely used in rubber products such as automobiles and machine tools due to their 

high filling content, good rubber elasticity and superior permanent deformation performance. Currently they are mainly used in high-value special rubber products 

such as polyacrylic acid resin rubber, fluororubber, nitrile rubber and ethylene propylene rubber, with the aim of maintaining the characteristics of synthetic rubber, 

namely high elasticity, low heat generation, low pressure change, flexibility, etc. Ultra pure carbon black has the characteristics of high purity and low impurities, 

with a sulfur content of less than 5PPM. It is also used as a reducing agent and carbon additive in the metallurgical industry.
