FIGHTS JAW FATIGUE
Innovative "Water-Free" Snorkel Manufacturer Selects
Thermoplastic Rubber Compounds from GLS Corp.
CARY, IL -- Design a better snorkel, and the diving industry will beat
a path to your door. That's happening now at DiVaire, Inc., manufacturer
of a unique, new snorkel that offers improved comfort, convenience and
water-free operation. Holding five U.S. patents (and more pending) on the
high-tech breathing tube, the company selected thermoplastic elastomers
from GLS Corp. -- Kraton ® (Sun Chemical Co.) and Dynaflex ® -- for
injection molding of key snorkel components.
Silicone, typically used in snorkels, was too hard a material for comfort,
decided Ben Delphia, DiVaire designer and company president. An hour
of clamping down on a silicone mouthpiece is a sure way to end up with
jaw fatigue. That, along with other shortcomings of snorkels, prompted
him to start working on a better design.
Delphia wanted a material with a softer durometer than silicon can
provide, and one that is recyclable, which is important to the company
and to many divers and snorkelers, he explains. Kraton and Dynaflex,
along with polypropylene, were chosen after a careful examination of
"I wanted a mouthpiece that was soft and comfortable enough to bite
down on all you want without any fatigue -- not hard and unforgiving
like silicone," he recalls. "I found that the Kraton and Dynaflex material
was ideal. It's almost like having bubble gum in your mouth."
Delphia notes that GLS was helpful in the selection of the thermoplastic
rubber compounds needed for the snorkel. "They were very supportive
of our needs when we were trying different durometers of materials and
in helping solve some of our processing and molding problems," he says.
"Some areas of the mouthpiece, for example, have to be very thick, and
some very thin. GLS helped us get over those early hurdles."
In addition to working closely with DiVaire in the development of tooling
and molds for the injection molding of the snorkel components, GLS
also provided assistance in color matching to achieve the bright "diver's
yellow" for the mouthpiece and accents, according to Delphia.
The end result was a snorkel vastly superior to others on the market.
Designed to keep water out for safer and more relaxing snorkeling, the
DivAire snorkel incorporates an internal Fluid Pumpô and a two-valve,
air intake/exhaust system. After a dive, any water left in the snorkel can
be easily cleared because of the position of the exhaust valve, midway
up the side of the snorkel. Water only has to travel half as far in the
DiVaire snorkel before being expelled as in a typical snorkel, which vents
through the top.
The same thing applies to exhaled air. CO²-laden, used air is expelled
out the side, without having to go all the way to the top. Fresh air comes
in through the top, and the snorkeler is able to inhale more of it. As a
result, less CO² is retained inside to be rebreathed. The quality of air
reaching the snorkeler is improved.
Designer Delphia credits the technical expertise provided by GLS as key
in achieving the processing flexibility needed for the product's complex
molding requirements. On the market since mid-January, the DiVaire
snorkel retails for $60 to $65 and is backed by a lifetime warranty
against defects in materials and workmanship.
Swimming is easier with the snorkel, due to its hydrodynamic shape,
which reduces water resistance. An integrated, mask-strap clip, made
of Kraton, provides quick release. Plus, the snorkel floats, for easy
retrieval. It comes in five colors, with yellow mouthpiece and accents.
All parts are made in the U.S.A., and the snorkel is 99% recyclable.
