The Progress of Biopolymers

Sunday, July 11th, 2010

For any reader who isn’t aware, most of the world’s plastic is currently made from crude oil. The process involves several steps, depending on the polymer that one is creating, but the total cost is still a fraction of the cost needed to create biopolymers of the same quality. Biopolymers are created by having a culture of bacteria consume large amounts of biomass. When the bacteria are mature, the culture is sterilized and the biopolymer is extracted directly. Many factors are now causing chemical and plastic companies to consider possible ways to reduce their reliance on crude oil, so reducing the cost of biopolymer production has become a greater priority. Since the polymer-using world cannot simply pay double or triple for things like plastic bags, plastic bottles, and plastic tubing, achieving this cost reduction is the missing critical factor to wide scale use of biopolymers.

The difference in cost between standard polymer production and biopolymer production is not caused by any one factor. Since the world uses such a large amount of plastic, existing polymer production facilities are huge, whereas biopolymers are mainly produced by small specialty groups and laboratories. Several companies are now considering the construction of large scale biopolymer factories, but they are waiting on the researchers to bring down the other areas of cost first. At present, it requires 3 times the weight in biomass to create a unit of biopolymer. This is because the bacteria being used are only able to consume certain nutrients from the biomass, leaving the rest behind as unusable waste material. Efforts are underway to find or engineer a more efficient bacteria for this task. The other side of the coin is to more effectively process the biomass such that a greater portion of it is consumable by the bacteria. Many different areas of research are currently being conducted toward this achieving this end, because labs and universities know the impact of these discoveries will be felt for centuries to come and the shorter-term breakthroughs could easily lead to a Nobel prize.

Got Air? Then you must have a custom medical tube.

Tuesday, March 16th, 2010

Custom Medical Tubing may not be the first thing people think about when it comes to the transfer of air, oxygen air and fluids—but if you work in the medical device industry, it’s likely on the top on your list.

And the reasons are clear—to help keep patients alive and well.
Manufacturing custom medical tubing must be executed following the strictest ISO compliant processes. Custom tubing manufacturers, who develop medical tubes which are generally used in diagnostic and interventional medical products, are required to perform its production in a Class 100,000 clean room. This ensures that the conditions under which the custom medical tube is made is adhering to those standards to result in a disposable end-product that is of the highest quality.

However, regardless of the material from which the custom medical tubing is made, these small diameter custom medical tubes can be extruded into a variety of shapes—circular, square, and oval. And while they can be more costly than other more conventional medical tubes, the expense is justifiable. After all, manufacturing custom medical tubing can be complex and need to be manufactured using the tightest tolerances specified to best suit the application.

In mission-critical procedures, the custom medical tube may be used as a nasal oxygen tube used on a post-operative patient. Medical tubes may also be involved in transferring fluids during transfusions or dialysis.

Research shows that PVC may be the leading polymer used for custom medical tubing, but most custom medical tubing manufacturing facilities can produce the custom medical tubes in a variety of thermoplastics.


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?
