Ptfe ring packing has high flux, low resistance, high separation efficiency and flexibility of operation.

● high temperature - long - term service temperature of 200~260 degrees

● low temperature resistance - still soft at -100 degrees

Resistance to corrosion resistance to aqua royalty and all organic solvents and inorganic compounds (except elemental fluorine, chlorine trifluoride and molten alkali metals)

● weather resistance - anti-aging in plastics.

● non-toxic pair of biological non-toxic also has more excellent chemical properties and chemical stability, is to make up for non-ferrous metals, various alloys can not solve the anti-corrosion, sealing and other aspects of the most ideal materials.
