29 July 2011- Many
industries use rubber tubing
purposes. In fact, various types of rubber tubing are used for different
applications. Two of such common rubber tubings are- Latex Rubber Tubing
and Silicone Rubber Tubing
. Both of these rubber tubing have their
own sets of advantages and disadvantages on the basis of which they have
their own preferences in various industries. This article aims at comparing
both- the latex tubing and silicone tubing with the viewpoint of making the
concerned people aware of their properties so that they might come to know â
which rubber tubing- Latex tubing or Silicone tubing- is perfect for their
Latex Rubber Tubing- Advantages
Rubber Tubing made from natural
latex is also known as surgical tubing, exercise or fitness tube, gum rubber
tubing etc. Those made with continuous dip process create superior natural
latex rubber tubing. whose physical properties are better and they also have
better quality and more vibrant colors than the synthetic rubber tubing or
the dry natural rubber tubes. Latex rubber tubing is comparatively cheap and
has relatively constant pressure. As such, they are also used for
manufacturing CPS water guns. CPS stands for Constant Pressure System- a CPS
is any water gun design which keeps pressure relatively constant. Latex
tubing is used in many fields including medical, scientific, industrial,
sports and recreation as well as for fitness therapies, especially as
Latex Rubber Tubing- Disadvantages
Latex Rubber Tubing
aside, latex rubber tubing has a few disadvantages too. Some of the other
disadvantages of latex rubber tubing can be listed as follows:
- The natural latex tubing, due to high protein content, is allergic
unless made in the proper way. The rubber tubing manufacturers who
consider lower protein levels in natural latex tubing while
manufacturing them produce non allergenic latex rubber tubes.
- Latex tubing has limited number of life cycles- less than twenty for
a particular tube.
- Latex tube may thin from tiny tears in the rubber.
- The potential flow is reduced by the size of a tubing barb. Smaller
inner diameter tubing has higher pressures but the tube itself reduces
the potential flow as the hole water must flow through is smaller. It
can be cured by using tubing barbs that are a little larger than the
inner diameter of the tubing.
- It is also tough to layer tubing to increase the pressure.
Silicone Rubber Tubing- Advantages
Silicone rubber is one of
types of rubber
that are easy to cure
and manufacture, cost-effective and have a consistent quality. Silicone
rubber sometimes prove better than many other organic rubber types and is
known for its wide range of complementary physical, mechanical and chemical
properties, some of which can be listed as follows.
- High- and low-temperature stability as well as compression resistance
- Silicone rubber is flexibility
- It has better tear strength , long-term tensile strength and
- Silicone tubings may be given varying degrees of softness and
- They are chemical resistant , ozone and oxidation resistance as well
as weathering and aging resistance
- ozone and oxidation resistance .
- As silicone rubber is fungus resistance, the tubings made from it are
widely preferred in the medical industry.
Silicone Rubber Tubing- Disadvantages
Silicone Rubber Tubing
rubber is not recommended to be used in most of the concentration of
solvent, oil, concentrated acid and sodium hydroxide being diluted. While
silicone tubing is preferred by medical industry but there is one
disadvantage of this tube which relates to its cleaning- it is difficult to
clean it and the inner tube (placed inside human body) may be more difficult
to reinsert than would a tube made of metal. However, it is believed that
the properties of silicone rubber
that of flexibility and comfort outweigh its disadvantages.
Latex Tubing and Silicone Tubing Compared
Many studies, especially
in medical field, have been conducted to test the suitability of surgical
rubber tubings made of latex and silicone. One of such comparisons of latex
and silicone rubber T-tubes draining the common bile duct in the Rhesus
monkey showed that both tubes excite an adequate local tissue reaction but
latex rubber degenerated more rapidly than silicone rubber. It was suggested
that silicone rubber T-tubes have a place in human biliary surgery,
especially when long-term drainage of the biliary tract is needed. Also, the
incidence of allergic reactions to latex is on the rise, the use of non
latex alternatives such as the silicone rubber tubing is increasing.
