The Properties and Advantages of PTFE Tube and PTFE Hose

Polytetrafluoroethylene or PTFE, also known as Teflon is a versatile ivory-white and opaque plastic fluoropolymer; it is composed of the free-radical polymerisation of numerous tetrafluoroethene molecules and is suitable for a number of applications in industries such as aerospace, the food and drink industry,  telecoms and pharmaceuticals.

PTFE tubes or PTFE hoses are made into different sizes or filled with carbon, carbon, stainless steel or many other materials to increase the wear resistance and strength.

Properties of PTFE

The main properties of PTFE are that it is highly flexible, thermally resistant, chemical resistant, non-stick and it is also composed of electrically resistant material.

The melting point of PTFE is around 327°C, and pure PTFE is also chemically inert, and also highly insoluble in most solvents or chemicals. It is also thermally stable and thus can be used between -200 degrees C and +260 degrees C without changing.

Other useful PTFE properties which set it apart from other pipes are its flexural strength, which is evident even in low temperatures. Besides its flexural strength, it has high electrical resistance and also dielectric strength, resistance to water because of fluorine’s high electronegativity and also the low coefficient of friction. That’s not all, PTFE’s density is pretty high, at 2200 kg/m3.

The Advantages of PTFE

 PTFE is really versatile, and it boasts of a wide number of applications. The benefits of PTFE can be utilised in manufacturing and engineering, for making tubes or liners and for handling or storing corrosive chemicals, also for coating parts such as bearings or screws to increase the shelf life of both the parts themselves and also the machinery they are part of.

A PTFE-coated screw will be corrosion-free, as PTFE can repel water and oil, and is also lubricated by the material to smoothly drive into the surface you are fastening to, with reduced friction, thus resulting in less wear and tear of the screw and the surface, and a secure and long-lasting finish.

A PTFE coat can extend the same benefits to screws, as it coats the screw it also makes it heat-resistant.

It’s true that the high-performance parts can ensure efficiency in machinery and reduce the need to replace parts, so it saves money and time and also reduces waste. This will further reduce maintenance needs and any expensive manufacturing downtime because of faults or repairs.

Cleaning of equipment can be drastically reduced in a few cases as a PTFE coat is non-wetting, thus facilitating self-cleaning of parts.

Add to that Teflon is also environment-friendly because, when it is applied to fabric, the finish will repel water and also oil stains which reduces the need to use dry cleaning, and fabrics will also dry up more quickly, with less energy with tumble drying, and it also lasts longer due to less wear and tear.

 PTFE is non-toxic, except for humans from polymer fume fever that is, only if the temperature of any Teflon-coated pans reaches above 260 degrees C. It is also FDA approved and food-safe, so this material has a great many benefits and can be used in many different areas.

PTFE Tubing: Process Parameters and Their Impact

PTFE Tube extrusion is considered to be one of the most difficult processes within the polymer space. All polymers have their typical properties and these properties impact both their processing and machining. PTFE tube comes with such varied process parameters, that every tube manufacturer will find it difficult to find a combination that works consistently.

 Parameters and their effect on the End-product

Whenever you think of PTFE processing one of the first things that are overlooked but needs our attention, is handling resin. Due to the structure of PTFE tubing, the fibrils that form extrusion depend on the strength of the final tubing. One of the reasons for the poor formation of fibrils is excessive shearing of the resin, before extrusion. This then, causes a dent in the achievement of good final properties.

·         Blending- Blending is one of the parameters which impact the final product and this can only be fixed with extensive trial and error. Unless the blending is done in the correct manner, the final extrudate will either be too soft or too dry. Also, if the blend is not uniform, the preform billet will have uneven densities, and the extrusion will then have quite a few issues.

·         Preforming-Preforming is mainly done to create a shape that can be fitted easily into the extruder. Preforming ideally has two functions: first, obviously, it gives shape and second, it also removes any air pockets from within the material. The process has to be done keeping in mind the one fact that too little pressure does not allow for an adequate venting of the air within the material. 

·         Extrusion-Extrusion is certainly one of the most important steps, as when the preform billet gets loaded into the extruder, then the preceding processes have already defined a lot of the tube’s most defining characteristics. However, it is also true that extrusion offers the tube its final shape and this process primarily helps maintain the adequate pressures on the billet at the same time ensuring the concentricity of the final tube. 

·         Sintering- When the tube is heated the temperature has to be heated for both a drying section along with a sintering section. The drying section needs have to be adequately warm to evaporate all traces of vapour from the tube. And, if it is too warm, the vapours may get ignited. Also, although PTFE does not melt, it may do so under its weight, it may even get elongated during sintering, causing changes in dimensional deviations. Therefore the temperature needs to be sent to make sure that the PTFE is able to reach the characteristic ‘gel state’ just before it goes out of the sintering chamber, so it can cool down when it reaches the room temperature. 

Apart from the above-mentioned parameters, PTFE tube also undergoes various other processes such as pigmentation, the addition of anti-static fillers and also the extrusion of specific profiles. Each of these requirements needs to undergo all of the above processes and understand how they need to be modified for a specific end-result.

What is the Difference between Hoses and Pipes?

Hose and tubing are sometimes used interchangeably but they do have one big difference that separates them. Hoses are typically reinforced in some way or the other.  Some of the common typical reinforcements are embedded braid reinforcement, reinforcement with a stiffer plastic or other material, wire reinforcement, a very heavy wall or dual walls. Between a hose and a pipe, a hose is generally used and rated for applications dealing with high pressure. On the other hand, tubing is not reinforced and is sometimes used for lower pressure applications or gravity flow.

In some cases, read applications both a hose and a tubing can be used. But when in doubt, about which one to use, the important thing is to ensure that the tubing or hose you select is according to the set of instructions advised by the manufacturer who states clearly how to handle them.

Hose and pipe can be described as lengthy hollow cylinders used to transfer and transport liquids. They are really very efficient in transferring liquids from one point to the other. Each hose or pipe is perfect passageways for different kinds of liquids used in industries and even at home.

Descriptions of Hoses and Pipes

What is a Hose?

A hose is a hollow-shaped tube which is created to transfer liquids from one end to the next. These are built according to application and performance. They are typically designed based on a number of things such as their weight, length, pressure rating, straight hose, coil hose and also chemical compatibility. There are a number of hoses which are demarcated according to their applications, such as fire hose, garden hose or air hose. They are generally used with spigots or clamps in order to keep a tab on the flow of the liquid.

What is a Pipe?

A pipe, such as PTFE hose pipe, is a tubular section or a hollow cylinder which is used to make substances flow from one end to another. This is typically utilized in a number of ways such as railings, structural applications, and fabrication. Tube and pipes can be interchangeable. However, according to engineering and the industry, these terms denote separate things and have separate definitions. Pipes are usually used for long-term purposes or even permanently. The flow of the liquids is also supported by tees and elbows.

Chief Differences between Hose and Pipes

The main differences between a hose and a pipe are as follows,

• A hose is much smaller than a pipe.
• The hose is made of a more flexible material when compared with pipes. Pipes are made up of rigid tubes. Hoses are made up of a number of materials which are polyethylene, polyurethane, natural or synthetic fibres like nylon while pipes are composed of metals, fiberglass, ceramic, plastic and concrete. 
• A hose usually has a circular cross section while other pipes may or may not have one.
• Hoses are mostly used at home and are seldom used in large industries while pipes are a permanent fixture in both home and large industries.
• When compared to hoses, pipes can be used in transferring substances that flow naturally such as powders, gases, and slurries.

Different kinds of hose such as PTFE braided hose and different kind of pipes are largely used today. There are various manufacturers who strive to make immaculate products looking to improve men’s ease of use of these materials.
