Comments Off on Here Are 6 Common Types of Teflon Coating

Teflon coating is one of the most common forms of coating with a wide variety of industrial applications. With incredible heat resistance, dielectric stability and low coefficient of friction, the material is more than just about non-stick surfaces.

Teflon coating can be applied on many materials, such as aluminum, steel, magnesium, glass, rubber, plastic and so on.

Let’s take a look at 6 common types of Teflon coating:

Teflon PTFE

Polytetrafluoroethylene or PTFE is the most widely used Teflon coating. Containing a primer and a top coat, the material has incredible engineering and industrial applications.

With a temperature resistance reaching as high as 500 degrees Fahrenheit, PTFE can handle the highest temperature rate among all the different fluoropolymers. Additionally, the material has low co-efficient of friction and high abrasion resistance. One drawback of the material is that it’s in fluid form.

Teflon FEP

Fluorinated Ethylene Propylene Copolymer or FEP is a completely non-porous film. Being perfectly non-stick, FEP coating makes the process of baking easier by melting and flowing.

The material offers great resistance against quite a few chemicals and is available in both liquid and powder form.

Teflon PFA

Similar to FEP, PFA or Perfluoroalkoxy offers non-stick coating. The material also melts and flows during baking. However, PFA has the capacity to deal with higher temperatures. Moreover, the material is stronger than both PTFE and FEP. It also comes in both liquid and powder form.

Tetzel ETFE

One of the strongest fluoropolymer, ETFE is a copolymer of ethylene and tetrafluoroethylene. It is sold by Teflon under the name Tetzel. Although the material is not fluorinated, it has remarkable chemical resistance and can operate at increasingly high temperatures. Its film can provide a superb durable finish. It comes in powder form alone.

Teflon One Coat

Composed of different blends of fluoroplastics and high quality resins, One Coat is a type of solvent-based coating that enhances the toughness and abrasion resistance. The coating works fine when applied to clean metals. Its components stratify during the process of baking and hence the material can retain its fluoroplastic properties like low friction.

Teflon Dry Lubricant

Dry lubricant is perfect for conditions that involve high pressures and velocities. Just like One Coat, this type of coating is also solvent-based. However, they are designed a bit differently to account for high pressures and velocities.

Comments Off on Understanding The Characteristics and Benefits Of PTFE Tubing

Polytetrafluoroethylene (PTFE) is an opaque, white fluoropolymer that is chemically created by free radical polymerization or multiple tetrafluoroethene molecules. PTFE is suitable for a wide range of applications in industries like automotive, aerospace as well as telecom.

PTFE is typically produced in the form of tubes or rods and comprises additives like stainless steel or carbon to boost strength and wear resistance.

PTFE Properties

If you were looking for a material that displays exceptional resistance to heat, chemicals, electricity while being highly flexible, you are actually looking for PTFE.

The material has a melting point of around 327 degree Celsius and is chemically inert. PTFE is also chemically stable between temperatures as low as -200 degree Celsius and as high as 260 degree Celsius without showing any signs of degradation.

Other highlighting properties of PTFE include:

Exceptional flexural strength, even in low temperatures

  • High electrical strength
  • High dielectric strength
  • High resistance to water
  • Lower coefficient of friction
  • High density (2200kg/m3)

In fact, PTFE is so chemically inert that, beyond being reactive to only a few chemicals—that too at high pressure and temperatures—the only thing you need to consider is that high energy radiation.

PTFE molecules tend to start breaking down under high energy radiation.

Properties Of Filled PTFE

While pure PTFE is subject to deformation under pressure, there are additives that can help. However, not all types of filled PTFE (modified) can be used in food and beverage applications.

Adding a filler to virgin PTFE can enhance its strength, add in electrical conductivity and enhance resistance to abrasion. On the other hand, fillers can also affect some of PTFE’s beneficial properties like chemical resistance.

From graphite to steel, fillers are usually dependant on the types of properties that need to be improved.

Benefits Of PTFE

The most important benefit of PTFE is the wide range of applications. From the outstanding benefits in engineering and manufacturing PTFE coatings can also be used to make parts like screws and bearings resistant to corrosion.

Some of the most important concerns regarding bearings and screws are wear and friction, both of which can be minimized using PTFE coatings. It also makes components exceptionally resistant to heat.

PTFE is also non-toxic and is food safe. It is also FDA approved, making it beneficial in a number of ways.

Comments Off on Outstanding benefits of PFA tubing

When it comes to transporting viscous liquids from one part of a facility to another, there isn’t a better option than PFA tubing. PFA is a lot similar to PTFE tubing in terms of characteristics and properties.

But what’s the difference? And why do some laboratories and industrial facilities prefer PFA tubing over other options? Here are some of the exceptional benefits of PFA tubing that make it the first choice for many industries:

Exceptional Pressure Resistance

When it comes to identifying the usability of tubing, pressure remains to be one of the most important concerns.

Pressure also helps realize the degree of safety that needs to be practiced when handling chemically active or hazardous liquids. PFA tubing guarantees ensures exceptional resistance even under large amounts of pressure. Even with this property, PFA tubing can be melted and reshaped for added convenience.

Reliable Temperature Stability

Working with chemicals or liquids also means that temperature comes into play. While one test may call for temperature to be set as high as 150 degree Celsius, another test could require taking that down to below freezing temperatures. However, most materials begin to deform, crystallize, or corrode under such extreme conditions.

Fortunately, PFA tubing resists extreme temperatures with ease. It can retain its shape and characteristics anywhere between -70 and 260 degree Celsius.

Relatively Lower Coefficient Of Friction

At times, even negligible amounts of impurities in tubing can lead to dramatic rises in friction, inevitably leading to errors and complications. However, this isn’t the case with PFA tubing. The formula used to manufacture PFA tubing ensures the lowest amount of friction. The surface of PFA tubing is barely porous, meaning that only small amounts of materials will be absorbed in the materials.

Useful Electric Qualities

Apart from handling hazardous and active liquids, PFA tubing can also be used as covering for electrical wires due to its unparalleled resistance to heat and low absorption characteristics. From valve linings to cable coatings, PFA tubing proves to be the perfect option for a number of different applications. With the right application, any insecurities over melting, damage or leakages can be eliminated.

PFA tubing also costs much less than many other options, making it the perfect combination of efficiency and affordability. Whether you are looking forward to large scale industrial application or to use it in laboratories, make sure you purchase PFA tubing from a reliable source.

Comments Off on Applications Of FEP Heat Shrink Probe Covers

FEP tubing offers the most comprehensive covering solutions for metal and other materials. Its lower shrink temperature among other fluoropolymers is one of the reasons why  FEP covers are preferred over PTFE and PFA. It’s also easier to install for shielding purposes.

Why FEP probe covers?

When it comes to probe covers, the best options are those which are chemically inert. The main reason for using probe covers is to prevent their exposure to harsh environment. It is necessary that probe covers don’t pose this threat and put sensitive equipment at risk of damage.

FEP is not only inert, but also resistant to high temperature. Encapsulating expensive equipment in FEP probe covers not only protects them from physical and chemical damage, but also ensures a longer life.

FEP covers are particularly used to protect stainless steel Thermocouples as well as RTDs and other sensor based equipment. These are used in various industries, ranging from automotive and aerospace to medical and food industry.

Most often, clear FEP covers are manufactured and used for covering. However, colored probe covers may be requested for certain applications, or for color coding different probes and equipment.

Common applications of FEP probe covers

  • In automotive and other mechanical industries, these probe covers are used to protect hydraulic hose and couplings against abrasions.
  • These are also used as protective probe covers in corrosive environment. Several medical devices and instruments take advantage of this feature for applications exposing probes to corrosive conditions.
  • Various temperature probes and thermometers are also covered to protect their specificity and sensitivity for detection. This increases the life of these probes and ensures accuracy.
  • FEP probe covers provide anti-fouling and contamination resistant shields to probes in medical, food, chemical and paint industries. As FDA compliant tubing material, FEP probe covers are safe to use for these applications.
  • These covers are also used for identification of probes and RTDs, in addition to providing protection against physical and chemical damage.

Our FEP probe covers provide high temperature heat shrink solutions, protecting sensitive equipment and probes from damage. Using a proprietary method, we manufacture pinhole-free seals for smooth, round covers ends.

You can do the encapsulation yourself, or let us do it for you. Your probes and other equipment will be encapsulated and returned within a day or two.
