Comments Off on Important Properties And Benefits Of PTFE Products

PTFE is a synthetic fluoropolymer that is typically opaque or ivory white. It is manufactured through free-radical polymerization of multiple tetrafluoroethene molecules. The exceptional properties of PTFE make it perfect for a number of different applications in pharmaceutical manufacturing along with food and beverage processing.

Even though we maintain a diverse variety of PTFE tubing products, they can be custom manufactured in any size and shape. Moreover, they can also be modified to boost certain characteristics like strength and resistance.

Properties of PTFE

If you are looking for a material that is highly resistant to heat, chemical reactions and electricity, while also displays an exceptionally low coefficient of frictions, you need PTFE.

PTFE has a dramatically high melting point (almost 327 degree Celsius). However, it is thermally stable enough to be used between temperatures ranging between 260 degree Celsius and -200 degree Celsius. The fluoropolymer is also highly insoluble in chemicals due its chemically inert characteristics. It can withstand the harsh conditions created by most acids and bases.

Other important properties of PTFE include:

  • Dielectric strength
  • Exceptional flexural strength (even in low temperatures)
  • High resistance to electricity
  • Highly resistant to water due to high electro-negativity of fluorine
  • High density
  • A significantly low coefficient of friction

The truth is, apart from a few chemicals, the only thing that needs to be considered when using PTFE is high energy radiation which can quickly break down PTFE molecules.

Benefits of PTFE

The most important benefits of PTFE include its wide variety of applications across different industries.

Apart from tubing or handling chemicals, the versatile characteristics of this fluoropolymer make it perfect for coating bearings, screws, and any other sliding machinery.

Take the example of a PTFE coated screw. It is able to repel oil and water, is inherently lubricated due to the coating which makes it easy to drive into a surface. At the same time, the low coefficient of friction results in lesser wear and a long lasting surface.

Similarly, friction can be an important factor with bearings. It can experience the same benefits as with screws, and also benefit from exceptional heat resistance.

Parts that are long lasting and resistance to heat, at the same time resistant to corrosion can contribute to the long life of machinery.

Comments Off on Explore the Various Types of Heat Shrink Polyolefin Tubing

Polyolefin is a thermoplastic polymer used in many industrial applications including manufacturing of different types of heat shrink tubing. Polyolefin is the material we commonly see as shrink wrap that is used to wrap and protect food and other consumer goods. When it comes to tubing, the typical heat shrinkable polyolefin tubing is highly resistive to chemicals, grease, moisture, fungus, and sunlight. It shrinks at temperatures above 121 degrees Celsius without splitting.

However, there are different types of Polyolefin tubing with different properties, and hence, different applications.  Here is an overview of some of the common ones found and used.

Thin Wall Heat Shrink Polyolefin Tubing

Thin wall heat shrink tubing shrinks up to 50 percent on temperature higher than 100 degrees. They are highly flexible and can be very effective from space saving point of view. It is mostly used for jacketing and identification of cables.

Semi-Rigid Heat Shrink Polyolefin Tubing

Unlike thin walled tubes, semi-rigid heat-shrink polyolefin tubing is tougher and less flexible. Due to its rigidity, it is also abrasion resistant. The tube diameter will shrink up to 50 percent when heated above 135 degrees. One factor that sets it apart from other heat shrink tubing is its flame-retardant quality.

Very Flexible Heat Shrink Polyolefin Tubing

Used in wire bundling in aerospace assemblies, this type of polyolefin rubbing has a lower shrink temperature and very high flexibility. Typically, the temperature is around 100 degrees. It is also highly flame retardant and therefore, it is used in applications where safety is extremely important.

Medical Grade Polyolefin Tubing

Medical Grade Polyolefin Tubing differs from other types due to its resistance to many chemicals used commonly in medicine, such as saline solutions, alcohol, and hexachlorophene. This tubing is flexible and also boasts an excellent dielectric property. It shrinks up to 50% on application on heat above 121 degrees.

Melt Wall Polyolefin Tubing

The purpose of melt wall polyolefin tubing is to protect the internal component against exposure to any harmful element such as moisture or chemical solvent. When heat above 135 degrees is applied to this tubing, the meltable wall inside the heat shrinkable jacket melts and flows in to fill up spaces around the inner surface. It solidifies as soon as temperature lowers and there remains no void for external elements to seep in and cause damage.

Comments Off on PTFE Tubing-One Product, Countless Applications

When it comes to fluoropolymer tubing, there are more than one resin with different make up and slightly different properties. While FEP and PFA are also commonly used for tubing, the most preferred polymer in this regard has always been PTFE or what we generally call Teflon.

PTFE Teflon tubing is preferred for several reasons and there are many factors that set it apart in tubing manufacturing. The first and foremost of the factors that make it a better option is its low coefficient of friction. If you didn’t already know it, it has the lowest of all the known solids. Other than that, it retains the innate properties of fluorocarbon polymers such as high resistance to chemicals, corrosion, and high temperatures.

So, what do all these properties mean?

It means that PTFE tubing is actually used in a multitude of industries and has a plethora of applications. Here are some of the common ones worth knowing.

Aerospace &Transportation

When it comes to aerospace and transportation technology, PTFE tubing is usually used inside a stainless steel mesh hose. These hoses work more efficiently than regular hoses with rubber tubing as Teflon is hardly affected by the abrasive qualities of fluids used in engines. Due to less friction, PTFE tubes can greatly improve the overall efficiency.

Medical

This may be one of the least known applications of PTFE tubes, but they are quickly replacing the regular tubes used for medical purposes. Due to high lubricity, the tubes are now being used in catheters as they prevent abrasive damage to any other organ or body part.  More and more medical caregivers and healthcare providers are now switching to PTFE tubes from regular tubes.

Chemical Applications

Chemical processing and manufacturing industries require containers and apparatus that don’t react to the product. Teflon is essentially the most inert and durable of all substances known and used in industries. Therefore, PTFE is generally used instead of glass, plastic, metal, or any other material that might react with the chemical contained in it.

Electronics

PTFE also has excellent dielectric properties that make Teflon tubes a well suited option when it comes to insulation of high voltage cables. PTFE tubing is also used for the purpose of isolating conductive surfaces in capacitors.

These are just some of the application of PTFE tubings. Click here to learn more about what makes PTFE the most preferred polymer for these applications.

Comments Off on Types Of PTFE Teflon Tubes And Its Uses

With the growing number of uses for PTFE tubes, it is definitely a challenge for manufacturers to cater to the varying demands across industries. Over the past two decades, PTFE tubes have made their way into different consumer, industrial and medical sectors in the form of pipes, coatings and other essential components.

The primary reason for the extensive use of PTFE tubing is the exceptional characteristics of this material:

  • Highly resistant to heat: The high resistance to heat means that this plastic has extremely high melting temperatures. This makes it perfect for use in industries where transportation of hot liquids is a daily operation.
  • Resistant to corrosion: PTFE is chemically inert, making it resistant to a wide variety of harsh chemicals and acids. It is also impermeable; therefore water cannot make its way through. This makes PTFE tubing the perfect option to transport chemicals.
  • Low coefficient of friction: With the low coefficient of friction (0.1), PTFE tubing is perfect for use in catheters and snares.

Types and uses of PTFE tubing

PTFE tubing manufacturers typically classify it in three different categories depending on the wall thickness and tube diameter:

  • Pressure hose
  • Spaghetti tubing
  • Pipe liner

Within these categories, there are further types and their different uses, as mentioned below:

  • Split: In these PTFE tubes, the wall consists of a ridge that allows the tubing to be split longitudinally. This enables medical practitioners around the globe to extract PTFE introducers from patient’s bodies without dislocating the primary device.
  • Heat shrinkable: This tubing is made using a very thin material. When the inside is exposed to hot air, it decreases or shrinks. This allows for manufacturing of wires and glass tubes along with other insulation purposes.
  • Multi-lumen: This tubing has a number of smaller tubes within a single interior. Each layer contains a different type of fluid or wire. Multi-lumen tubes are used across a number of applications in the medical industry.
  • Filled: This tubing involves chemical additives to give the tube radioactive properties. This is yet another important type of PTFE tubing in medical applications as it is visible in X-rays. Fillers are also utilized where anti static properties are required.

Therefore, PTFE manufacturers consider multifarious applications when manufacturing products. If you are looking for reliable PFA and PTFE tubing, get in touch with us today.
