PTFE Sheet Organic solvents

English abbreviation for PTFE (commonly known as "plastic king"), trade name Teflon ®. This material products with acid and alkali resistance, high temperature, anti-organic solvent characteristics. In the chemical and pharmaceutical industry is widely used, called the originator of the pad industry.

Introduction to editors

Teflon (English abbreviation for Teflon or PTFE, F4), because the application is widely known as the "plastic king", the Chinese transliteration called "Teflon", "Teflon", "Teflon", " Teflon "," Teflon "and so on.

Polytetrafluoroethylene is made of polytetrafluoroethylene polymer compounds, with excellent chemical stability, corrosion resistance (is the world's best corrosion resistance of one of the materials, in addition to molten metal sodium and liquid fluoride , Resistance to all other chemicals, boiled in the king of water can not afford to change, widely used in various needs of anti-acid and alkali and organic solvent conditions), sealing, high lubrication non-stick, electrical insulation and good anti-aging , Temperature span (can be in the temperature of + 250 ℃ to -180 ℃ long-term work).

Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoate (PFOA), is thought to be carcinogenic.

Its birth to solve the world of chemical, oil, pharmaceutical and other areas of many problems. It has been widely used as a sealing material and filling material.

Performance Benefits Edit

High temperature - use operating temperature up to 250 ℃.

Low temperature resistance - with good mechanical toughness; even if the temperature dropped to -196 ℃, can also maintain a 5% elongation.

Corrosion resistance - for most chemicals and solvents, showing inert, strong acid and alkali resistance, water and a variety of organic solvents.

Resistant to climate - the best aging life in plastics.

High lubrication - the lowest coefficient of friction in solid materials.

No adhesion - is the smallest surface tension in the solid material and does not adhere to any substance.

Non-toxic - with physiological inertia, as artificial blood vessels and organs long-term implantation in the body without adverse reactions.

Teflon as a sealing material has a variety of applications. Because of its high corrosion resistance, physical stability, high and low temperature resistance, the achievements of its good sealing performance, in the petroleum, chemical, pharmaceutical, power, steel industry has a wide range of applications. Suitable media include water, oil, acid solution, alkaline solution and almost all chemical components.


Soft polytetrafluoroethylene refined. Durable and reliable sealing performance; Teflon itself has the best corrosion resistance and non-aging, after a special processing has a good creep resistance and resistance to cold flow; in a wide temperature range of long-term safety Use; soft and easy to cut, can be cut by mechanical or manual, easy to install.
