Virgin PTFE is capable in its own right, but when mineral fillers, such as molybdenum sulfide, are added, it enhances the material wear and deformation characteristics to more fully exploit their unique combination of chemical, physical and electrical properties.
Molybdenum Disulfide (PTFE-MoS2): Added in various amounts (5% to 15%), increases hardness, stiffness, and wear; minimal effect on chemical and electrical properties.

APPLICATIONS:Slide covers;Bearings, bushings.
ADVANTAGES:Good sliding and wear characteristics;Low cold flow;Good thermal conductivity;Low coefficient of friction;Reduced chemical resistance;High pressure resistance

Can ptfe be used on gas?

2017-12-27 16:19:05 | PTFE
When connecting gas pipelines and their fittings to a stove, grill or other connection, it is important to use Teflon tape designed for gas connections and not Teflon tape designed for water pipes. Teflon tape seals the gas fittings' threads and keeps leaks from developing. The Teflon tape for gas fittings is available at hardware, home improvement and plumbing supply stores.
Can ptfe be used on gas
Teflon tape for gas fittings, also known as gas-rated Teflon tape, is yellow in color and clearly states it is for gas lines and connections. The tape works on all gas line types, including butane, propane and natural gas lines. 
Apply gas-rated Teflon tape only to the fittings' threads. Do not apply the tape to gas compression connections, the removable nuts and bolts used to connect two gas pipes together. Gas fittings are on the ends of gas lines and are not removable. Turn off all gas connections at the gas meter outside your home or business before disconnecting or attaching gas lines to appliances.
After applying the tape, connecting your gas lines and turning the gas back on, mix 2 teaspoons dishwashing liquid and 1 cup of water in a pot. Dip a cloth or rag in the soap solution and swab the solution on the gas fitting. If you see bubbles forming on the fitting, you have a gas leak. Immediately turn off the gas source and tighten the gas fitting. Then turn the gas back on and test the fitting again. If the solution is still bubbling, turn off the gas, disconnect the fitting and check the fitting for dirt, debris or damage. Clean the fitting thoroughly, and reapply gas-rated Teflon tape. Repeat the testing process. Have a professional replace the gas line if the soap solution continues to bubble.
If you use plumber's Teflon tape on gas pipe fittings, the tape will degrade over time and gas vapors will escape from the fitting. Plumber's Teflon is white in color and thinner than yellow gas-rated Teflon tape. Leaking gas pipes and fittings are dangerous and can cause an explosion. If you are uncomfortable applying gas-rated Teflon tape to gas fittings, contact a plumber or repairman specializing in gas connections and repairs to complete the gas pipe installation or repair.

Can PTFE be recycled?

2017-12-25 15:29:55 | PTFE
PTFE (Polytetrafluoroethylene) plastics are generally opaque, and are an excellent barrier to gas, moisture, and resistance to heat. PTFE shows a remarkable chemical resistance and it is insoluble in all known solvents. It is attacked only by molten alkali metals and fluorine at high temperatures. PTFE has excellent resistance to acids, alkalis and solvents. It is very lubricous, with the lowest coefficient of any polymer. The chemically inert plastic is easy to clean and has exceptional mechanical resistance under extreme conditions. In addition, PTFE is autoclavable and non-flammable.
PTFE does not have it's own recycling code symbol. However, PTFE can be recycled into many other products. Recycled PTFE can be used for rods, tubing, tape and more. 
PTFE Recycled
Polytetrafluoroethylene (PTFE) is a synthetic material accidentally invented in the late 1930s. It was when a chemist was trying to develop a new type of perfluorethylene-based refrigerant. Rather than achieving a chlorofluorocarbon, the scientist found that the perfluorethylene used in the process reacted with the iron content of its container and polymerized under pressure.
This new material was distributed on a commercial scale and was eventually known as PTFE. After several decades later, it was known as the first non-stick kitchenware.
Where is PTFE is used?
It is used for applications where sliding parts are needed like plain bearings, gears, and slide plates.
Powdered PTFE is used in pyrotechnic compositions as oxidizers together with powdered metals.
PTFE is also used in optical radiometry. Sheets made from PTFE are used as measuring heads in spectroradiometers and broadband radiometers because of its capability to diffuse a transmitting light nearly perfectly.
PTFE is also used to coat certain types of hardened bullets to prevent the increased wear on the firearm’s rifling that would result from the harder projectile.
It is also used laboratory materials such as containers, stirrers, and tubing.
It is used as a thread seal tape in plumbing applications.

Why is PTFE used in electronic components?
PTFE has exceptional insulating properties that make it ideal for electronic components. It is non-conductive, meaning; it is resistant to high electric fields. It is also resistant to heat, water, and chemical corrosion. It is also used on producing laboratory equipment and accessories that come into contact with hydrofluoric acid.
PTFE possess a very low frictional property. This makes PTFE suitable for manufacturing parts that need to resist friction like ball bearings and gears.
Other characteristics of PTFE
  • * an excellent barrier to gas, moisture and heat
  • has remarkable chemical resistance and is insoluble in all known solvents
  • attacked only by molten alkali metals and fluorine at high temperatures
  • has excellent resistance to acids, alkali and solvents
  • very lubricous
  • can be sterilized by autoclave, gas, dry heat and chemical disinfectant
  • Disadvantages of using PTFE
One of the most common uses of PTFE is for cookware. PTFE pans cannot be used if you see scratches or cracks on it. It cannot be used after it deteriorates. It begins to deteriorate after the temperature of the cookware reaches 260 ˚C and decomposes above 350˚C. This degradation by-product can be lethal to birds and can cause flu-like symptoms in humans.
Issues in recycling PTFE
Like any other materials, recycling decreased the properties of the original material. In PTFE, many of its properties are good that it is still feasible after recycling. In some studies, 5-10% ration would still allow the material to pass off as pure PTFE. One of the main issues with recycled PTFE is that it is not applicable for long term uses.
But, to sum it all up, recycled PTFE will always have inferior properties to PTFE and cannot be consistent over time. It is always better to expect that it can be compromised and that it is priced a little lower than the original.
