The properties and advantages of PTFE:
High temperature resistance - working temperature up to 250 C.
Low temperature resistance - good mechanical toughness; 5% elongation can be maintained even when the temperature drops to - 196 C.
Corrosion resistance - For most chemicals and solvents, it shows inertia, strong acid and alkali resistance, water and various organic solvents.
Weather resistance - the best aging life of plastics.
High lubrication - the lowest friction coefficient in solid materials.
Non-adherence - is the smallest surface tension in solid materials and does not adhere to any substance.
Non-toxic - physiological inertia, as artificial blood vessels and organs long-term implantation in vivo without adverse reactions.
Polytetrafluoroethylene (PTFE) as a sealing material has many applications. Because of its high corrosion resistance, stable physical performance, high and low temperature resistance, it has achieved good sealing performance, and has been widely used in petroleum, chemical, pharmaceutical, electric power, iron and steel industry. Applicable media include water, oil, acid solution, alkali solution and almost all chemical components.
