Hydrodynamics. Snorkeling enthusiasts should check out what its makers claim to be the "future of snorkeling." The DiVaire snorkel, produced by DiVaire Inc., Walled Lake, MI, incorporates six patents in a design said to be technologically advanced and hydrodynamically styled for comfort and durabilityWHEN THESE ARE SOLD THERE ARE NO MORE, THEY SHOULD BE A COLLECTIBLE BECAUSE OF THERE UNIQUE DESIGN . "Before our snorkel, 'sophisticated' snorkeling equipment really had not progressed much beyond a tube to take in air and clear out water," says Ben Delphia, the snorkel's designer and DiVaire president. Conventional snorkel tubes trap air and water in the tube when submerged, and, after surfacing, they leave behind carbon dioxide that is inhaled with fresh air. Over time, the CO 2 build-up can cause headaches and fatigue. The DiVaire snorkel eliminates that problem by letting fresh air enter through the top of the snorkel, which is curved downward to discourage water entry. Used air in the system is expelled, with the help of the internal deflector and fluid pump, through a side exhaust valve located just above the water line. The valves work in two ways to keep water out: the top valve seals shut when the snorkeler submerges so no water can enter; the one-way side valve only allows air and water out KRATON® SNORKEL

Innovative "Water-Free" Snorkel Manufacturer Selects
Thermoplastic Rubber Compounds from GLS Corp.

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. de, 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."
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.
