Excellent
question. The answer? Miracle "Polypropylene". The entire hull
is made of this stuff! Frankly, without it there could be no folding
Porta-Bote.The hinges are absolutely water tight and are so unique
they have been granted international patents.
So,
what exactly is this copolymer? It's an exotic engineered resin
originally developed by the U.S. Aero-Space industry. It has incredible
properties. The hinges can take stress of over 90,000 pounds per
square inch. They have been designed so that the higher the pressure
on the hinge the more it "wants" to remain sealed. The Porta-Bote
Polypropylene hinges have been modulus tested at a rate of over
500,000 openings and closings without failure.
Also,
our formula utilizes an ultra-violet (UV)
filter. This renders the material unaffected even by exposure
to saltwater. It won't even burn! This same formula is presently
being used in the manufacture of the new "lifetime" batteries,
automobile bumpers, bullet proof vests, Astro-turf, and
even non-rusting highway road signs. How long will it last? We
have inspected 25+ year old Porta-Botes and they looked almost
as good as new!
That's
right...the hinges and hull material have now both been time-proven
for 31
years by almost 60,000
satisfied customers, worldwide! That's why
we can offer our famous 10 year
limited hull material warranty.
