What are inflatable rafts made of?
Boat makers use two general types of coated materials: synthetic rubber, such as NRS’s Pennel Orca® (Hypalon® or neoprene), or plastic polymers (PVC or urethane) in their inflatables. If you can see both sides of the material—from a tear, loose seam or by removing a valve—you should be able to tell.
Why was Hypalon discontinued?
The environmental pressures, high manufacturing costs, hazardous nature of manufacturing the product, as well as commercial pressures all probably contributed to DuPont’s decision to discontinue the production of their Hypalon products.
What is the strongest inflatable material?
The Hypalon-coated fabric with polyester, nylon or neoprene interior is known as the most reliable and durable inflatable boat fabric, so many inflatable boat materials choose Hypalon as an exterior coating because Hypalon will last the longest out of any other inflatable boat material.
How long do Hyside rafts last?
The floor of a self bailing raft is a wide flat inflated chamber. When inflated, the floor is about 4 or 5 inches thick, so the top surface of the floor is above the surface of the water.
PVC (Plastic Coatings)
|Expected life expectancy under normal river rafting use||10-15 years||2-3 years|
Are NRS rafts good?
They’re a great value but tend to not be as durable and well made as the American-made rafts. 1. NRS offers a huge variety of boat styles made from a variety of materials. Their warranty is between 1-10 years depending on the material and style of boat.
What replaced Hypalon?
Hypalon was discontinued by its manufacturer (DuPont) and is now sold under its slightly different formula and new name “CSM” or Chlorosulfonated Polyethylene Rubber.
Can you use acetone on Hypalon?
Methyl Ethyl Keytone and acetone are solvents for PVC and the color of the fabric should come off on a clean white rag used to prepare the surface for gluing. … MEK and acetone do nothing to Hypalon or Neopreme.
Is Hypalon the same as neoprene?
Hypalon as it is now known in the marine industry today is a remarketed version of the old Hypalon using an additional layer of neoprene (cr) so the new chemical formulation is csm/cr.
Is PVC or Hypalon better?
Generally speaking, CSM/Hypalon RIBs are more expensive – sometimes more than twice as – but they also are much more resilient to UV exposure and to accidental gas, oil, or chemical exposure, such as fuel spills, than their PVC counterparts. … However, PVC RIBs have their pros as well.
How long do PVC rafts last?
PVC inflatable boats will last anywhere between 2-10 years depending on the manufacturer, the use, and care it receives. Welded PVC boat will outlast those made with glues/adhesives. Hypalon (CSM) boats usually last 7-15 years, but can last as many as 20 years.
Are PVC RIBs any good?
As a result PVC boat production can be mechanized to a greater degree thereby providing cost effective manufacturing. … However due to their lack of resistance to prolonged exposure to UV rays and chemicals they are not typically used in larger RIBs which tend to be left exposed for longer periods in direct sunlight.
