Comments Off on A Complete Guide to Using Teflon Tubing

Resist Heat and Corrosion

When you use Teflon PTFE tubing, you use tubing that resists more than just heat. It’s known for having a rather high resistance to corrosion. Think of it as a protective shield for your cables, acting as the wall that keeps both the heat and the corrosion on the outside. You want neither of those to intrude on and potentially damage your cables, as you don’t have time to deal with heat-damaged cables or corroded ones. Find PTFE Teflon tubing manufacturers who can help you.

Extra Benefits

When it comes to PTFE tubing, Teflon tubing does more than protect your cables from corrosion and unwanted heat. It also protects the cables inside from water damage while preventing things from becoming overly sticky. This is one of the best options for environments where moisture and cables are in close quarters with one another. If corrosion wasn’t enough, this kind of tubing has high resistance to chemicals. Stop harmful chemicals dead in their tracks with the best Teflon PTFE tubing.

Split Tubing

There are multiple kinds of Teflon PTFE Tubing. For starters, split tubing has specialized walls. Because of this advantageous property, the tubing itself can be split longitudinally. Generally, this kind of tubing is used within the medical world. It can make things easier for medical practitioners since they don’t have to dislocate a primary device in some medical applications. It just helps them when something needs to be removed from a patient.

Heat Shrink Tubing

This might be the kind of tubing that you want to use to repair or keep your cables intact. Using heat shrink tubing is rather easy since all you really need to do is add heat to it. Then, it will shrink around whatever is inside the tubing itself. When it comes to using this kind of tubing for manufacturing, it’s good for manufacturing both glass and wires. In addition, it can also be used for insulation purposes.

Filled

One of the more unique kinds of tubing is filled tubing. This kind actually comes with radioactive properties. This is because it has various chemicals added to it, which causes the tubing to acquire a few extra properties. Similar to split tubing, filled tubing also has medical applications. When it’s inside the body, X-ray photographs will make it visible, allowing doctors to easily locate anything with the tubing covering it.

Cutting the Tubing

When the time comes to actually cut the Teflon tubing, you can normally rely on four different options. You might not actually need a specialized cutting device. You could just use a pair of shears or a razor blade. These two options are recommended mainly for home use. However, if you want the cut to be more precise, consider getting some tubing cutters. If you need the best cut possible, work with a company that has access to tube cutting lasers, which are proven to be highly effective.

Your Next Application

Teflon PTFE tubing might be the answer to your next application. Whether you’re working in the medical field or you have a manufacturing project, this tubing might be the best product for your upcoming project. Whether you need to use heat shrink tubing or filled tubing, you should be able to locate exactly what you need from a trusted seller. When in doubt, ask them what they might recommend.

Comments Off on Using PTFE in Aviation and Aerospace Industry: An Overview

Polytetrafluoroethylene (PTFE) is an incredibly versatile fluoroplastic that has become invaluable in several industries but has been particularly vital in the aviation and aerospace industries. While available in one form or another — the most famous brand name of a PTFE product is Teflon — since the 1930s, this synthetic fluoropolymer of tetrafluoroethylene has several remarkable properties, which is why it plays such an important role in the success of both the aviation and aerospace industries.

Unique Characteristics

Both aerospace and aviation rely on materials that are light, durable, and versatile. For several reasons, PTFE is the only material to succeed so brilliantly at meeting the demands of these advanced systems of transportation that no other product will do. For instance, PTFE is hydrophobic, meaning it’s resistant to water. Combined with the fact that it’s also extremely heat resistant, it’s an ideal substance for fuel cables and cable insulation in the form of heat shrink PTFE tubing. Due to the fact that PTFE has one of the lowest coefficients of friction of any solid, it’s ideal for protecting parts of vehicles where aluminum and other metal sections are liable to rub against each other. In this manner, it serves a dual purpose of both decreasing friction and limiting vibration, which is why it’s such an effective material in places such as in the leading edges of airplane wings.

Improved Safety

Modern aircraft simply could not function without all that PTFE has to offer. Like the rest of the airplane, it’s a lightweight material, allowing aircraft to fly more efficiently. The aerospace sector operates with the highest safety standards imaginable. PTFE serves an important role in allowing aerospace engineers to design ever more sophisticated machines knowing that they’ll have the materials available to them that will meet the extremely high Aerospace Material Standard.

Dielectric Properties

The excellent dielectrics properties of PTFE — especially at high radio frequencies — makes it perfectly suited for insulation in cables and connector assemblies. Clear heat shrink PTFE tubing has a far higher melting point than the polyethylene more commonly used in applications that don’t have to withstand the rigor associated with the aviation and aerospace industries. It’s also a common product used in computers and circuit boards both within and without these industries who still rely on computers for their operations.

PTFE Film

Commonly utilized in the production of fiberglass composites — as well as carbon fiber composites — PTFE film acts as a barrier between fiberglass or carbon parts as they’re being built. This makes it possible to manufacture products without non-production materials adhering to the parts as they’re being constructed. Such purity in the manufacturing process is of particular importance as it relates to the aerospace industry where impurities can be especially damaging.

Whether it’s due to its resistance to heat, its dielectric properties, or its low friction coefficient, PTFE has become one of the most relied upon materials throughout the aviation and aerospace industries. With over 50 years of experience in manufacturing PTFE, Tef – Cap Industries Inc. knows all about this remarkable material and its many applications.

Comments Off on Thin Wall PTFE Tubing: Different Applications Explained

Tube

The demand for PTFE tubing is growing, mainly because it is so versatile that it can be used in almost every industry imaginable. From medical devices to electrical wiring tubing to piping, the list of applications for thick and thin wall PTFE tubing is impressive and expanding! Here is why and how it is used.

Reasons Why PTFE Tubing Is So Popular

Heat Resistant: Some PTFE tubing can withstand regular exposure to plus 500 degrees Fahrenheit temperatures. Almost all PTFE tubing thin wall is highly resistant to heat. This makes it ideal for applications where exposure to hot liquids is routine. Additionally, its resistance is not countered by it becoming brittle when not exposed to heat, which means maintenance costs in high heat applications is minimal. The heat range it can be exposed to is approximate -450 degrees to 500 degrees Fahrenheit, making it easily the most diverse tubing in regard to temperature on the market. That diversity makes it popular across applications and industries.

Corrosion Resistant: A thin wall PTFE tube is mostly inert when exposed to other chemicals. This means that there are almost no adverse reactions when exposed to a wide variety of harsh chemicals and acids. Additionally, it is impermeable, which means it is water and air tight, even in areas that are subjected to high heat or harsh substances. These two factors in regard to durability and resiliency make it ideal for the transport of chemicals. It also adds to the safety quotient of anything it is transporting as the only way it will leak is if it is physically punctured as opposed to being eaten or worn away by a corrosive element.

Extremely Low Friction Coefficient: Light wall PTFE tubing has a very low friction coefficient (0.1,) which makes it ideal for applications where friction can be dangerous or painful. Two examples are catheters and snares. The low friction ratio makes using both much easier than with a substance with a higher friction coefficient. In fact, smooth bore thin wall PTFE tubing has the lowest friction coefficient of any known solid materials.

Applications

PTFE tubing comes in three main categories:

  • Pressure Hose
  • Spaghetti Tubing
  • Pipe Liner

Its wall thickness and tube diameter determine the type.

Within each category, PTFE is further classified:

Split: This consists of a ridge that permits splitting longitudinally. It is used by medical personnel internationally to extract PTFE introducers from patient bodies without dislocating the primary device.

Heat Shrunk: Tubing of this sort is very thin, and it decreases or shrinks when exposed to hot air. This allows for air and watertight fit. It makes it ideal for securing small and thin components like wire.

Filled: With this application, the tubing is infused with chemical additives that give off radioactive properties. That makes it visible in X-rays and where anti-static properties are required.

Multi-Lumen: Tubing applications of this type have a number of smaller tubes in a single interior. Each layer contains a unique fluid or wire. These types of applications are common in the medical industry.

In many ways, PTFE tubing has reinvented certain types of manufacturing. It is used in the science and medicine fields, medical device industry, with electrical wire producers and automobile manufacturers. Best of all, it seems new applications are being discovered all the time. For more information on PTFE tubing and whether it is right for your manufacturing needs, check out Tef-Cap.
