Let’s get started.
Are PTFE And Teflon The Same Material?
PTFE and Teflon are the same material usually used as a synonym for duplicate materials.
Primarily, the word Teflon is a brand name for polytetrafluoroethylene (PTFE) registered by DuPont in 1944.
Moreover, Teflon-PTFE is a fluoropolymer with several properties that make it extremely useful.
Some of its distinctive properties are described as follows:
Basso attrito
Teflon consists of extremely low friction that is why it is marketed as being non-stick.
Alto punto di fusione
Due to its high melting point, Teflon applies to the inside of frying pans
Good Temperature Resistance
Teflon has impressive temperature tolerance and remains stable up to around 260°C (500F)
Chemical Inertness
Mostly, PTFE does not react with other materials, which makes it susceptible to many applications.
Resistenza chimica
Furthermore, it can resist attacks from chemicals such as acids, alkalis at high temperatures.
However, in certain circumstances, it can be attacked by halogens under alkaline conditions.
Also, the PTFE does not react with non-polar solvents, e.g., oils or greases.
Che cos'è il PTFE?
PTFE (Polytetrafluoroethylene) is a synthetic fluoropolymer of tetrafluoroethylene.
Due to its hydrophobic, non-wetting, high density, and temperature resistance properties, PTFE is an incredibly versatile material with many applications.
Moreover, the PTFE comes as white powder or flakes, which you’ll often find at craft stores.
Furthermore, the material is not very soluble in most solvents; instead, it clumps up.
Chemically, PTFE benefits from being blended with another substance called a coupling agent.
Eventually, this agent helps PTFE to break down into tiny particles, making it dissolve more readily.
Consequently, PTFE can be converted to a liquid by combining with a solvent like acetone in the correct proportions.
However, it’s also possible to mix PTFE powder directly into other resins.
Subsequently, powder PTFE is often used as a filler for resin which improves the material’s rigidity and gives it additional strength.
Moreover, mixing PTFE into epoxy, polyester, or even silicone rubber will create durable and stiffer materials.
Can PTFE be durable and stiffer materials, Machined?
Yes, PTFE can be durable and stiffer materials while processed through a machining process.
Moreover, CNC machining PTFE is the mechanism of stamping, molding machined components out of PTFE.
Technically, CNC machining PTFE uses methods very similar to machining other plastics.
However, sharp tools are required for good results because of their low strength.
Consequently, the machining process can modify the physical properties of the material through the degradation of molecular structure.
Practically, CNC machining PTFE has a slightly lower coefficient of friction than that before machining.
Eventually, it requires more torque to rotate at a given speed about unmodified material.
Moreover, these CNC machining PTFE parts are durable and resist their shapes even after years of use.
While other machined parts experience loss in performance after only a few hours of use.
Mechanically, the machining process used for PTFE is similar to that used for plastics and metals.
Typically, milling, turning and drilling methods are extensively used for PTFE materials.
Commercially, PTFE is machined into different parts of products like molds and dies, automotive parts, electrical insulation components, etc.
Furthermore, various industries allow the machining of CNC machining PTFE components, from medical devices to aerospace applications.
What are the Advantages of PTFE Machined Parts?
The advantages of PTFE machined parts are stated below:
Cost Saving
PTFE machined parts are the way to cut costs by ensuring that you have a strong material that will hold up against high temperatures.
Moreover, PTFE is a good material for machining, as it cuts cleanly without the need for drills or inserts.
However, drills can be used at much higher speeds than standard high-speed steel tools.
Consequently, this reduces the effort and cost of producing parts, making it easier to produce precision parts with smooth finishes.
Can Withstand Harsh Environments
PTFE is a synthetic material that can withstand harsh environments without reacting with the chemicals it comes into contact with.
Unlike other materials, PTFE will not break down or erode in this type of environment because it can resist moisture and prevent corrosion.
Self Lubrication
PTFE offers the lowest possible friction, which means it’s perfect for creating parts that need to move against other objects.
Subsequently, this makes PTFE an excellent choice for self-lubricating mechanisms or relevant product design.
Moreover, it does not have any porosity, so there are no weak spots after machining.
However, it can be a wise decision to contact a professional manufacturer and ask for a quotation.
If you are looking for the best manufacturer of PTFE machined parts, then DEK is the best choice for obtaining precisely machined parts.
Is PTFE Abrasion Resistant?
Yes, PTFE is abrasion-resistant and due to its chemical inertness and insolubility in organic liquids or steam.
Consequently, this means it won’t wear away or dissolve away, allowing it to adhere both to fluids and solids (i.e., pipe fittings).
Moreover, it has low creep strength under stress-relieving conditions, making its handling challenging.
Generally, this property needs to be accounted for while designing applications to prevent it from deforming over time under compressive stress.
Furthermore, it has a low coefficient of friction against stainless steel or silicon carbide while exhibiting good lubricity over other materials.
What Are The Applications Of CNC Machining PTFE?
The applications of CNC Machining PTFE are as follows:
Application in Wire Insulation
Commonly, PTFE is used in wire insulation for applications that require a higher temperature tolerance, mainly in high voltage transformers.
Technically, the PTFE is processed as extruded rubber sheets that are then cut into strips and molded to make them safe for high voltage applications.
Application in Thermal Coupling for Insulation
The plastic forms a seal between two pieces of metal (usually copper) with the heat conduction property.
Though the thermal coupling provides insulation but also conducts heat through conduction.
Application in Bearings to Reduce Friction
Another application of Teflon’s high coefficient of friction and inertness is the linear motion system bearings or ultra-smooth parts that slide against each other.
Use in Air Track
One example is an air track where the airflow suspends small objects beneath them due to differences in air pressure.
This application requires two plastic sheets on either side of an aluminum base, with PTFE strips forming a seal between them at all contact points.
Technically, PTFE is used here due to its little friction capable of sealing the surface efficiently.
PTFE Vs. Other Plastics, How To Select For My CNC Machined Parts?
Among PTFE and other plastics, to select for your CNC machined parts must be the one with effective and high-performance properties.
Generally, PTFE is different from other plastics in the following ways:
Typically, PTFE does not leach molecules of metals like copper and iron when heated during food preparation.
Moreover, PTFE does not contain BPA-an industrial raw material used to make polycarbonate plastic and epoxy resins.
However, it can be a concern as it can act like the reproductive hormone estrogen in humans, initiating or enhancing puberty development in children.
Consequently, PTFE containers are inert under normal storage conditions, i.e., they do not release ammonia gas or other toxicants that would later be absorbed into the food and cause harm.
PTFE doesn’t produce the “acrylamide” issues in plastic cans-a a potential neurotoxin found in Belgian-style fried potatoes, french fries, chips, etc.
Usually, this chemical is formed when heating the food and included in cancer-causing chemicals when taken at higher doses.
Furthermore, PTFE can be an ideal pick for food products since it can not convert into harmful substances and completely save for human use.
However, apart from food products, plastics are suitable for normal use.
