Pennel Orca Boat Material
Since 1994, NRS has used Pennel's "Orca" material in
manufacturing our Expedition and Otter rafts, River Cat and Kodiak
cataraft tubes, and MaverIK inflatable kayaks. Pennel originally used
DuPont® Hypalon® as a coating on their Orca material. Because of the
Hypalon coating, inflatables built with Orca fabric – including these
NRS designs – were commonly referred to as Hypalon boats.
Hypalon is DuPont's name for the chemical compound chlorosulfonated
polyethylene (CP), which the company invented in 1940. In April 2010,
DuPont stopped making Hypalon and Pennel needed to find another source
of high-quality CP. They did; and extensive testing has shown that the
newly sourced CP provides the same superior performance that our
customers have come to expect from NRS boats.
Over the years,
CP has proved to be an excellent material for making boats. First of
all, it's great at holding air... a most important feature for
inflatables! It's also super abrasion-resistant, UV-resistant and
chemical-resistant. Other uses for CP include roofing materials and
liners for chemical treatment lagoons – so you know it's tough stuff!
You'll no longer see the term "DuPont Hypalon" used to describe NRS
boats (or any other manufacturer's boats). Look for "NRS Pennel Orca"
instead – along with the uncompromising quality that has made NRS a
worldwide leader in inflatable boats.
