Qingdao Chaorui Nanotechnologies was established in 2005 at Qingdao, Shandong Province, China, focusing on the R&D, mass manufacturing of various carbon nanotubes. The factory covers an area of 30, 000 square meters. Up to 2020. Our annual capacity has reached 500 tons. The carbon nanotubes can be used in Lithium batteries, composite, painting, rubber, silica gel, etc. Our carbon nanotubes can entirely or partially replace black carbon in the above specific areas. Additionally, we are exploring the use of some modified carbon nanotubes in more areas.
