PTFE and PTFE lined Products
PTFE can be used for strong acid (Sulfuric acid, hydrochloric acid), strong alkali (NaOH, KOH, LiOH, Ca(OH)₂) and all kinds of organic solvents, and the plasticity is better, the operation temperature ranges from -180～260ºC, so it is the best choice of chemistry plants, concentrator plants.
