Polytetrafluoroethylene is a polymer compound obtained by polymerizing tetrafluoroethylene PTFE SEPTA. It has excellent chemical stability and corrosion resistance (it is one of the best materials for corrosion resistance in the world today, except for molten metal sodium and liquid fluorine). It can withstand all other chemicals, and it does not change in aqua regia. It is widely used in various working conditions requiring acid and alkali resistance and organic solvents.) Sealing, high lubrication, non-stickiness, electrical insulation and good aging resistance. Long temperature resistance (can work for a long time from +250 °C to -180 °C).
Performance advantages: high temperature resistance - use working temperature up to 250 °C.
Low temperature resistance - good mechanical toughness; 5% elongation even at temperatures down to -196 °C.
Corrosion resistant - inert to most chemicals and solvents, resistant to strong acids and bases, water and various organic solvents.
Weather resistant - the best aging life in plastics.
Highly lubricated – the lowest coefficient of friction in solid materials.
Non-adhesive - is the smallest surface tension in solid materials and does not adhere to any substance PTFE SEPTA.
Polyethylene PTFE gasket is assembled with PP cover, which is used with automatic hplc vials . It has the advantages of acid resistance, alkali resistance and good sealing.
This is the end of the introduction of Introduction of polyethylene PTFE Septa. I hope it can help you.
