Difference between PVC and Hypalon tubes for inflatable boats
If you own or are considering buying a RIB or inflatable boat, the choice of floatation material is crucial. Many boat owners wonder about the exact difference between PVC and Hypalon. This difference determines how long your boat will last, how much maintenance it requires, and how well it can withstand sun, salt, and other weather conditions.
What is PVC?
PVC is a plastic to which plasticizers are added to make it flexible. This makes it ideal for inflatable boats. It is lightweight, affordable, and easy to process industrially.
At Zodiac, PVC tubes and boats are thermally welded, creating a strong, airtight bond between the material layers. This isn't the case with all brands, and it's precisely this that ensures the quality you expect from Zodiac.
A major advantage of PVC is its light weight. A PVC boat is easy to carry, store, and inflate quickly. Moreover, the price is often two to three times lower than a Hypalon tube.
PVC does require a bit more maintenance. Sunlight and saltwater can affect the color or texture over time. Regularly cleaning your boat with approved maintenance products, such as those from Blue Marine , will keep the material strong and vibrant.
What is Hypalon (Neoprene-Hypalon)?
Neoprene-Hypalon is a combination of two high-quality rubbers: neoprene (CR) and Hypalon (CSM). This material is primarily used for professional RIBs and rescue boats due to its exceptional durability. However, even Zodiac's larger RIBs are supplied exclusively with a Neoprene-Hypalon float.
While PVC is welded industrially, a Neoprene-Hypalon float is handcrafted. The seams are sanded, glued, and precisely finished. This makes the production process more expensive, but the result is a tube that is more resistant to UV radiation, saltwater, and chemicals.
A Hypalon boat requires less maintenance than a PVC boat. The material ages more slowly, remains flexible, and retains its color and texture much longer. While the initial price is higher, this is recouped in longevity and lower maintenance costs.
PVC or Hypalon: what do you choose?
The right choice depends on how and how often you sail:
- PVC is ideal for recreational use, for example for a few months per year.
- Hypalon is the best choice for intensive or professional use, or if you sail year-round and the boat is exposed to the elements for long periods.
Whichever option you choose, it's important to maintain your boat properly. Rinse the tubes with clean water after each use, don't leave your boat in direct sunlight for extended periods, and always use products specifically designed for inflatable boats, such as Blue Marine maintenance products.
How do you recognize PVC or Hypalon?
- PVC is recognizable by its light texture and welded seams (like those found on Zodiac boats). Both sides of PVC are the same color. The back of PVC is always glossy. When you sand PVC, no sanding residue is released.
- Neoprene Hypalon, on the other hand, usually has a smooth texture (except for special versions like Carbon , Fabric Impression , or Honeycomb ) and glued seams. Lightly sanding Hypalon will release fine sanding dust. Over time, small "hairs" may develop on the edges of a Hypalon boot. The back of Hypalon material is (almost) always gray and not shiny, which is a clear distinguishing feature.
Conclusion
The difference between PVC and Hypalon determines the lifespan, maintenance requirements, and performance of your inflatable boat. PVC is lightweight and affordable, while Hypalon is stronger and more durable. The best choice depends on your boating style and frequency of use.
