Scope of application:
　　It is applicable for all kinds of corrosive chemicals, including strong corrosive liquids (such as liquid strong alkali, hydrochloric acid and sulfuric acid), organic solvent and liquid nitrogen, etc. It is used in the sealing for flange, valve, reaction kettle and pump of industrial equipments in industrial fields such as petroleum, chemical industry, chemical fiber, coal cutting, generating power and metallurgy, etc.
Features:
　　This packing is mainly ameliorated the defects of poor heat conductivity and small thermal coefficient of PTFE. It adapts to the sealing positions with high pressure and high velocity, has little wearing to contacting site and its starting torque is small.
