See how various neoprenes hold up under pressure
Note: Like other parts of our web
site, this one is still being developed. When complete, you will be
able to see samples of all the commonly used neoprenes under various
pressure readings.
It's easy to tell you that Wetwear NCN (nitrogen composed
neoprene) and Rubatex G-231NBN (G-231 nitrogen blown neoprene) are
the best neoprenes for divers. You may have already confirmed that
elsewhere. There' s nothing like seeing it for yourself. Our
compression chamber has samples of the best neoprene grades for
diving that most of the major neoprene manufacturers provided. It
also has samples of the Wetwear NCN and Rubatex G-231NBN grades we
use, in various thicknesses. See for yourself how they compare.
So sure are we that Wetwear NCN and Rubatex G-231NBN is the very
best neoprene for diving, that we extend this offer. If you get a
sample of any diving grade neoprene you think may do as well, mark
it with your name and send it to us. We will put it in the chamber,
photograph it and include it on our web site so the world can see
it.
Keep in mind that for years, we've had neoprene manufacturers
contact us stating they had something as good as Wetwear NCN and
Rubatex G-231NBN, some saying it is even better. We had them send us
samples of their best neoprene for diving, tested them in our
chamber, and confirmed that marketing people don't know what the
truth is, or at least don't repeat it. Their neoprene fell flat.
Thus far, none have been anywhere near as good as Rubatex.
The chamber
What began as a science project for our son Eric several years
ago has turned into a valuable business tool for us. It's great to
be able to demonstrate to people in seconds what we've known for
years, that Wetwear NCN and Rubatex G-231NBN neoprene resists
compression more than others and will keep you warmer. We use the
chamber in our store to show customers the truth about neoprene. We
also take it with us to the various consumer shows we do, and even
to DEMA when we used to go there.
The chamber consists of a small compression chamber with a
pressure gauge mounted atop it. It is powered by aluminum scuba
cylinders located in the base (about 42 inches tall, a little over a
meter) that feed air through small high pressure lines that come up
through the base to the chamber itself. There is a fill switch on
the lower left that is depressed to pressurize the chamber. The
pressure relief/empty switch is located on the back of the unit and
is not visible in the photographs.

The test
When demonstrating the chamber test in our store, we start at
surface pressure and begin pressurizing the chamber. We stop briefly
at each additional atmosphere of pressure (approximately 33 ft, 66
ft, 99 ft.- 10m, 20m., 30m, etc.) taking it deeper for those divers
go go deeper. After a brief pause, we then begin depressurizing,
again stopping at each atmosphere. The visual results are amazing,
as you can see for yourself. Wetwear NCN and Rubatex G-231NBN
compresses less and recovers faster than other neoprene. It lasts
longer over time as it is more compression resistant and durable and
retains its flexibility and warmth retention capabilities longer.
