TCF (chlorine-free) is a process of bleaching paper pulp with H2O2, ozone, peracid such as peracetic acid, persulphuric acid, biological enzyme and other oxygen-containing chemicals, and it is very safe and reliable without using any chlorine-containing bleaching agent. No carcinogen dioxin is produced in the production process. No irritation to skin, no harm to human body and no harm to environment.
Chlorine bleaching may produce carcinogen dioxin. The equivalent toxicity is equivalent to 130 times of cyanide, a well-known toxic substance, and 900 times of arsenic!
