PTFE Rasch ring packing has the advantages of large flux, low resistance, high separation efficiency and flexible operation.

● High temperature resistance: a long-term use temperature of 200~260 degrees

● Low temperature resistance -- still soft at -100 degrees

● Corrosion resistance of Aqua regia and all organic solvents, inorganic compounds (except element fluoride, chlorine trifluoride and molten alkali metal)

● Weather resistance - anti-aging in plastics.
