Riddled with Medical Tubing Supplier Questions?

Tuesday, March 16th, 2010

If a person is only as good as their word; then it would stand to reason that a medical tubing supplier is only as good as their…tubes, right?

Medical tubing suppliers around the country offer their customers a wide range of services in manufacturing custom tubing. However, what makes one medical tubing supplier stand out for the competition? After all, not all Medical Tubing Suppliers are created equal.

It’s not a trick question, but a real one that design engineers should consider when they are shopping around for the best medical tubing supplier to meet their custom tubing needs.

One such defining competency is a medical tubing suppliers expertise in a particular configuration of tubing, for instance, do they specialize in small diameter custom tubing?

Why this is important may not be immediately evident, but if you consider that while technology keeps advancing, the components installed in the equipment are designed to more exacting specifications—i.e., precision small diameter tubing.

OK-what does that translate into for the design engineers and the medical tubing suppliers?
Well, take thin wall tubing for example used in a sensitive piece of medical equipment—chances are its tolerances need to be tighter but it still needs to retain its mechanical characteristics of being flexible, durable, etc.; but the thermoplastic initially selected may be challenged in being extruded for this new small diameter custom tubing’s specifications.

But who would have the expertise to make that discernment for their customers? One would venture a guess and state that it would take the design and manufacturing insight of an experienced medical tubing supplier who specializes in small diameter tubing.
Wouldn’t it?


The ABC(D)’s of PVC clear tubing

Tuesday, March 16th, 2010

The benefits of PVC clear tubing are evident if you ever used it—but if not, and you’re looking for a clear choice, no pun intended, when selecting the appropriate tubing for the job, PVC clear tubing should be on the top of your list.

Some key reasons why people choose PVC clear tubing:
(A) Suitable for multitude of applications due to its ease of use and installation such as for medical devices, air lines, and pools and spas, to name a few.

(B) Provides for a versatile and inexpensive choice to replace many other plastic piping applications, especially when it is necessary in circumstances where visual monitoring is necessary, as in potable water systems.  And when the necessity for “glass-like” clarity such as that found in clear PVC tubing is critical—such as for chemical companies.

(C) PVC clear tubing is resistant to corrosion. This makes clear plastic tubing an ideal choice for medical and hospital use.

(D) PVC tubing provides outstanding flow characteristics which assists in the prevention of bacteria and sediment buildup in the clear tubes, which makes it a top choice for food processing facilities.

And another simple fact, and often times a driving factor as to why companies select PVC clear tubing concerns new EPA regulations. For many industries, such as the automotive and industrial sectors, complying with new standards for safety and energy efficiency require that they replace older tubing or pipes that transport hazardous materials—and PVC tubing is the suitable choice.

The reasons are simple and the list numerous other than these few key attributes of clear PVC tubing listed here.  But if you need more information, contact a reliable PVC clear custom tubing manufacturer.


Polycarbonate tubing…it’s for the birds

Tuesday, March 16th, 2010

Polycarbonate tubing may have a tough exterior, but you can see right through it for all the durable characteristics clear polycarbonate tubing offers, even from your living room window.

Now the birds may not thank you, but you can be assured that next time you notice one of them safely feasting off the seed contained in your birdfeeder, it’s was all because of the polycarbonate tubing.

Recognized for its “chew-proof” qualities is only one of the reasons why polycarbonate tubes are chosen for use in bird feeders. This durable clear polycarbonate tube is designed to keep seed safe from squirrels, cats or other predators. Better yet—clear polycarbonate is eco-friendly and safe to use; and given the growing number of consumers who are opting for eco-friendly products, it would seem reasonable that the market demand for polycarbonate tubing would increase.

Of course, polycarbonate tubes are not only applicable for use in birdfeeders by environmentally-conscious consumers.

In many other applications that require that the tubing be unbreakable, multiwall polycarbonate is an ideal choice due to its dielectric strength and ability to withstand high temperatures. As such, polycarbonate tubing is ideal for use in electronic appliances were its components may be subjected to conditions that could compromise its function.

But whether you’re an a distributor of bird-feeder supplies, like polycarbonate rod or are looking to custom manufacture your companies own line of polycarbonate tubing for a variety of other industries, you can be assured that the polycarbonate tube will provide your customers with a lifetime of use.


Which Poly Tubing is right for you?

Tuesday, March 16th, 2010

Poly tubing means different things to different users because it covers such a wide breadth of products.

Do you require an extrusion with radiopaque materials? Then single lumen tubing is an ideal poly tubing selection.

Perhaps you need limitless options in manufacturing poly tubing because your application is complex and requires multiple channels—then multi-lumen clear tubing may work best.

The ability for customer tubing manufacturers to make poly tubing from a variety of thermoplastic materials adds to it being adaptable for a number of other uses. For example:

  • Polycarbonate is chosen when customers need toughness, clarity and high-heat tolerance are need from the poly tubing. This thermoplastic is often selected for poly tubing used in conduits or appliances.
  • Polyethylene is specified when small diameter poly clear tubing needs to be flexible and withstand repeated flexing with marginal negative impact. It has excellent chemical and gas resistance which makes it perfect for those in the medical industry.
  • Polypropylene tubing is quite versatile with a high heat tolerance and therefore is a perfect material for fiber spinning, laminating, injection molding, etc.
  • And when the poly tubing is going to be exposed to potential harsh conditions, polyurethane is select as it is abrasion and tear-resistant.

One of the key benefits of custom manufacturing poly tubing is its relatively low costs, and its compliance with FDA, USDA, NSF, and UL regulations. This makes it an ideal choice for leading industries when they need high performance and quality from their poly tubing.


No sun block necessary for thermoplastic tubing

Tuesday, March 16th, 2010

Typically speaking, U.V. light and ozone have been known to cause health damage to humans, but what are its effects on thermoplastic tubing?

Depending on the length of time thermo plastic tubing is utilized in certain applications—whether it’s exposed to ozone or to UV light—will determine which polymer is used to manufacture the thermoplastic extruded tubing. Taking material selection into consideration, and then adding a UV stabilizer, for example, lowers the risk that excessive exposure to potentially harmful environmental conditions cause that may compromise the performance characteristics of the thermoplastic tube. Several thermoplastic extrusion materials include polycarbonate, polyurethane, polypropylene, as well as custom compounds.

The importance of thermoplastic extruded tubing being able to withstand UV damage means different things to different people depending on the industry.

For those in the medical industry, some active agents in certain drugs will degrade when exposed to UV light. Therefore, it’s critical that the thermoplastic rod be UV resistant, such as that of thermoplastic polycarbonate that will block harmful rays from damaging the effectiveness of medications.

If the thermoplastic tubing will be subjected to outdoor applications, then custom tubing manufacturers may recommend the use of either thermoplastic polyethylene tubing or thermoplastic polypropylene tubing. As this type of exposure accelerates the deterioration rate of certain chemical properties that thermoplastic tubing is comprised of. Both will deliver reliable performance against environment stress cracking, which could cause leakage of fuels and oils.

As demonstrated, damage caused to thermoplastic tubing by long exposure of either the ozone or UV light has negative effects to be avoided. So before you select your thermoplastic tubing, consult with your custom tubing manufacturer.


Extruded Profiles…of Courage

Tuesday, March 16th, 2010

What defines courage?
Short list: strength, confidence and taking action despite the conditions that threaten your success. While the definition of courage is subjective, for those who work in the medical industry that have to demonstrate courage at every turn—it requires those attributes and many more. But believe it or not, one of their single most important tools to assist them is extruded profiles.

Extruded profilesare utilized in a variety of applications from medical device components, processing aids and medical instruments. Something as simple as a PVC plastic tube acts as a conduit to sustain life in many cases; such as that used as a catheter that’s inserted into a patient’s heart. And having high quality PVC extruded profiles provides this life-saving equipment with the versatility, flexibility and durability it needs to assist medical personnel to do their job.
So when custom tubing manufacturers and design engineers are in the development phase of extruded profiles, they take into consideration the end user of the product and the extruded profile application. It’s not just a matter of ensuring that profile extrusions are cost-effective to satisfy the bottom line, but they also need to take into account particular parameters during the design of the extruded profiles to ensure it will perform during any mission-critical application.
Characteristics such as, will the PVC profile extrusion:

  • Perform reliably
  • Be resistant to chemicals
  • Demonstrate UV and heat stability
  • Maintain rigidity

After all, it’s these parameters and more that medical professionals rely upon to ensure that the extruded profiles they are utilizing, whether made in urethanes, PVC, or custom compounds will facilitate the success of any medical procedure.

Go with the [clear nylon tubing] flow

Tuesday, March 16th, 2010

Thanks to scientists at DuPont back who invented nylon in 1931 numerous industries have been afforded the opportunity to manufacture a myriad of products because of this highly durable “miracle fiber”—products such as clear nylon tubing . And if you live in the Northeast, you may appreciate its introduction to the industrial world even more so—particularly knowing that clear nylon tubing is available for purchase.

Being exposed to freezing temperature during the winter months can cause its share of problems. Before you know, it’s only early January and a coat of ice has covered everything from your walkway to a tree limb. But did you also know that your well pump could be comprised if you’re not using clear nylon tubing?

The last task you want to be undertaking in the winter is a tubing replacement project for your well pump, which is why clear nylon tubing is highly recommended for this application purpose. It will not become brittle or swell because of water. And best of all—nylon tubing can withstand subfreezing temperatures.

With a high quality clear nylon tubing installed, you can be assured that if the pump stops working and no water is running through the tubing, that the clear nylon tubing will continues to perform in these harsh conditions when the pump becomes operable again.
And given clear nylon tubing’s resistance to corrosion and stress-cracking the result is obvious– you have flowing water!

Who would have thought that clear plastic tubing could be one of the single most important components to transport a water supply?


Have it your way—but can it be manufactured?

Tuesday, March 16th, 2010

Unless you’re a design engineer of custom made tubing you may not be as curious as to how custom tubing is made, or why it is important to consider custom tubes specifications closely before embarking on the manufacturing process.

More often times than not, tube designers push the manufacturing envelope when they design custom made tube with requirements that are not necessarily advantageous for the products intended use. It’s not intentional to make the manufacturing process of custom tube more difficult, rather a goal of developing the perfect end product.

But what they should be asking themselves during the design phase is, “what are our critical requirements for this product?” Otherwise, what is often realized too late can be costly and also cause delays in production of the custom made tube. To avoid such stumbling blocks, there are several criteria that tube designers should consider during the custom tubing planning process:

  • Material specification – have you considered the best thermoplastic suited to the application of the custom made tube?
  • Configurations – are your design specifications realistic so that the custom tubes can be manufactured?
  • Manufacturability – is your design dimensions and tolerances feasible and would you consider re-evaluating your tolerances to facilitate the process of making a high quality custom made tube more efficiently?

From the time that plastic was first introduced into mass production, custom tubing companies have been afforded the opportunity to create a myriad of products from extruded plastic rods to single-lumen tubing. And like the world of imagination, custom made tubes have endless possibilities—but proper planning will make it a success.


Polypropylene tubing vs. Steel tubes in solar heating systems…and the job goes to?

Tuesday, March 16th, 2010

Curiosity may have killed the cat! But curiosity about the benefits of polypropylene tubing used in solar heaters is a different story altogether. This is particularly true whether you’re a design engineer responsible for making decisions concerning the tubing material for solar heating equipment, or a homeowner deciding to install a solar heating system.

Here’s why.

While polypropylene tubing may be used in a number of applications, its potential use in solar water heaters spawned scientific interest.  A recent study reported on its experimentation of testing whether polypropylene tubing would perform better than steel tubes in the heat transfer rates.   It was concluded that polypropylene tubes would in fact be the ideal choice, over steel tubes, as the polypropylene rod increased the rate of heat transfer by 10 degrees Celsius.

Based on these results, one could conclude that design engineers may specify polypropylene rod in the design of solar heating systems; passing those benefits on to the end user, in this case, the homeowner. As not only is installing a solar heating system with polypropylene tubing suggested to be environmentally beneficial, it also offers a cost-savings benefit in two distinct ways: First, users will save on energy costs by using solar heating, and second, they can also take advantage of a federal tax credit offered to taxpayers for installing energy efficient systems.

Of course, this is simply a cursory view of the benefits of polypropylene tubing.  But it may just be your link to your finding a custom tubing manufacturing source that will serve your polypropylene tube needs — whether for a solar heating system or any other application deemed appropriate.
