Applications of PTFE

Petrochemical and chemical processing: PTFE is the material of choice for gaskets,vessel linings,pumpinteriors,washers,rings,seals,spacers,dip tubes and well-drilling components because it is corrosion resistant and chemically inert; it is unaffected by virtually all acids and caustics and functions in environments to 500degrees F..

Electrical applications: PTFE is one of the best insulators known. In thin sections, it will insulate to 500 volts per mil. There are grades of PTFE which have been even greater dielectric strength. It is frequently used in wire and cable wrap, and to separate conductive surfaces in capacitors.

Semi-Conductor Industry: PTFE is insert, and its operating temperature range is from minus 350 degrees Fahrenheit to 550 degrees Fahrenheit. When made to ultra pure standards it is the material of choice for various items used in chip manufacturing

Food,Beverage and pharmaceutical industries: Virgin PTFE is approved by the FDA for use in the food,beverage,cosmetics and pharmaceutical industries. Thin film and sheets make an inert,no-toxic slide surface without microscopic depressions where microbes can grow.

Laboratory applications: PTFE piping, tubing and vessels are used in various laboratory ware because of their chemical resistance, and inertness..

PTFE Compounds: Various fillers can be blended with the PTFE base resin to enhance certain properties, e.g. glass fiber, glass bead, carbon, graphite, molybdenum disulfide, bronze, etc.

Advantages of PTFE

High temperature resistance: The working temperature is 250℃.

Low temperature resistance: Good mechanical toughness; even if the temperature drops to -196℃, it can also maintain a 5% elongation.

Corrosion resistance: For most chemicals and solvents, it shows inertia, strong acid and strong alkali, water and various organic solvents.

Climate resistance: The best aging life among all plastic.

High lubrication: The lowest coefficient of friction in solid materials.

Non adhesion: The smallest surface tension in the solid material, which does not adhere to any substance.

No toxicity: It has a physiological inertia and has no adverse reaction in the long term imolantation of artificial blood vessels and organs.

Electrical insulation: It can resist 1500 volts of high voltage electricity.
