PTFE flat pad

Polytetrafluoroethylene gasket, abbreviated as PTFE, has the characteristics of acid and alkali resistance, high temperature resistance, and resistance to various organic solvents. It is widely used in the chemical and pharmaceutical industry due to its high corrosion resistance, stable physical properties, and resistance to high and low temperatures, achieving excellent sealing performance. It is widely used in the petroleum, chemical, pharmaceutical, power, and steel industries. The applicable media include almost all chemical components such as water, oil, acid solutions, alkaline solutions, etc.

Polytetrafluoroethylene is a polymer compound polymerized from tetrafluoroethylene, which has excellent chemical stability and corrosion resistance (it is one of the materials with better corrosion resistance in the world today. Except molten metal sodium and liquid fluorine, it can resist all other chemicals, and does not change when boiled in aqua regia, and is widely used in various conditions that require resistance to acid, alkali and organic solvents), sealing, high lubrication, non adhesion, electrical insulation and good aging resistance, and has a large temperature resistance span (it can work at a temperature of+250 ℃ to -180 ℃ for a long time).

High temperature resistance - operating temperature up to 250 ℃.

Low temperature resistance - with good mechanical toughness; Even if the temperature drops to -196 ℃, it can maintain a 5% elongation rate.

Corrosion resistance - exhibits inertness towards most chemicals and solvents, and can withstand strong acids, alkalis, water, and various organic solvents.

Climate resistant - with better aging life in plastics.

High lubrication - refers to the lower friction coefficient among solid materials.

Non adhesive - it is the smallest surface tension in solid materials and does not adhere to any substance.

Non toxic - with physiological inertness, as an artificial blood vessel and organ implanted in the body for a long time without adverse reactions.
