Hypalon (a rubber cloth) or PVC are the two materials used to make inflatables. Before you start repairing an inflatable, you need to know what kind of material was utilized to make it.
If you’re trying to mend a tear, it’s usually easy to distinguish whether cloth is which since Hypalon has various colors on the outside and inside, whereas PVC has the same color on both sides.
Today, all Zodiacs are constructed of Strongan, a PVC material developed by the company. However, numerous models were manufactured of Hypalon before to 1968.
This means that unless the boat was built before 1968, any repairs you undertake yourself will require Stabond as the adhesive. In that instance, before deciding whether to use Stabond or a Hypalon adhesive, you’ll need to confirm the material as described above.

What materials are used to make inflatables?
Inflated structures can be made out of a variety of various types of inflatable fabric. However, a sound structure starts even before these procedures, with the fabric, or material, that is chosen. Materials, particularly in air-supported structures like inflatables, have a critical influence in a structure’s function. Because they don’t have much of a frame, the fabric must bear the entire weight of the structure.
To boost their strength and resilience to the elements, inflatable fabrics are usually coated or laminated with synthetic compounds. Polyvinyl chloride (PVC) coated vinyl or nylon, as well as oxford woven cloth, are among the most commonly utilized materials. Materials with a PVC coating are more durable and more expensive.
Many elements go into deciding the sort of inflatable fabric to use. One of the most essential considerations for inflatable makers is whether the inflatable structure will contain “impact regions.” Slides and bounce surfaces, for example, must be extremely durable. Can you see the impact zones on the inflatables in the picture below?

Zodiac inflatables are made in the United States.
Nearly 90% of the RIBS sold in North America are made at Zodiac’s North American production facility in Summerville, South Carolina. For the entire Zodiac global operation, the Summerville factory also supplies the Yachtline and Bayrunner Series.
Why was Hypalon dropped from the market?
DuPont, the original maker of Hypalon, stopped producing it in 2009. This was owing to concerns about production safety and the environment. For starters, when Hypalon burns, it produces extremely poisonous vapors. In the plastics business, these vapors have been scrutinized and are classified as an air contaminant. Furthermore, Hypalon contains lead-based compounds, which are well-known for their risks and limitations.
As a result of this change, the market for material considerations in RIB boat manufacture has shifted. Manufacturers had two options: they could use off-brand Hypalon (CSM/CSPE) suppliers or they could use new, superior materials like Thermoplastic Polyurethane (TPU).
Why is Hypalon preferable than PVC?
PVC or CSM/Hypalon fabric is used in almost every inflatable boat. So, how can you figure out which one is best for you?
CSM/Hypalon RIBs are generally more expensive than PVC counterparts, sometimes more than twice as much, but they are also far more resistant to UV exposure and accidental gas, oil, or chemical exposure, such as fuel spills. CSM/Hypalon RIBs are best for individuals who plan to own the RIB for 10 years or more, or if it will be used as a major mode of transportation or for long-term sailing. They are also more shock and impact resistant.
PVC RIBs, on the other hand, have their advantages. When price is a factor, or if you live in a mild area with a short boating season, PVC may be the preferable option. Furthermore, if the boat will be stored out of the elements/sun, it will retain its air a little better than CSM due to its structure.
Regardless of which model you buy, keep these tips in mind to get the most life out of your inflatable:
- When looking at PVC boats, seek for Mehler-Valmex Mainstream Plus fabric with an acrylic surface finish. When looking for CSM/Hypalon kinds, look for the Orca brand.
- Look for clean, even, wrinkle-free seams and minimal brown glue residue in the construction details.
- Only get a PVC boat with welded seams if you’re looking for one.
- Check for sturdiness in D-rings, grab grips, and davit lifting points.
- Working with brands with strong local sales and service representation as well as global networks is a fantastic idea.
- Clean your RIB with soap and freshwater on a regular basis. Covers for your investment are a low-cost insurance coverage.
- Always inflate your RIB to the manufacturer’s suggested operating pressure when in use!
How can I tell whether my inflatable is made of PVC or Hypalon?
PVC has tiny overlaps and welded impressions, while Hypalon is glued and has a lot of material overlap. Because PVC is a thinner material, it also displays fabric print-through.
What are the elements that make up the zodiac signs?
The 12 signs of the zodiac, as mentioned in a horoscope, are inextricably linked to the Earth’s motion through the sky. The constellations that point out the path that the sun appears to take during the year provide us with these indicators. Dates in a horoscope may appear to match to when the sun travels through each constellation. They don’t always agree, though, because astrology and astronomy are two separate systems. Plus, a closer look at the Earth, the sun, and the stars reveals that the zodiac is more complicated than you might think!
The sun’s motion through the constellations
The sun appears to pass in front of numerous constellations as Earth revolves the sun. The sun’s position in relation to distant background stars drifts in an easterly direction from day to day, much how the moon appears in a little different spot in the sky each night. It’s not as if the sun isn’t moving. Its movement is totally fictitious, owing to Earth’s own rotation around our star.
The sun appears to be in front of, or “in,” different constellations throughout the year. The sun appears in Gemini one month and Cancer the next. The dates in the newspaper’s horoscope indicate when the sun is in a specific astrological sign. For example, the sign Aries is represented by the period between March 21 and April 19. However, your astrological sign does not always indicate which constellation the sun was in when you were born.
Why the zodiac constellations don’t always align with astrological signs
We need to know a little bit more about how the Earth moves to explain why constellations no longer coincide with their respective signs. We must also discuss how we measure time.
Time is a fiendishly difficult concept to grasp, especially if we insist on using the sun and stars as our point of reference. For better or worse, our calendar is based on the seasons. The day the sun appears at its most northerly point in the sky is June 21, the approximate date of the summer solstice north of the equator and the winter solstice south of the equator. The North Pole is most inclined towards the sun at the June solstice.
The fact that the North Pole does not always point in the same direction as the background stars complicates things. Our world whirls around like a top. The Earth, like a top, wobbles! The North Pole traces a circle on the celestial sphere due to the Earth’s wobble. The wobbling is slow; it takes 26,000 years to complete one rotation. However, as time passes, the effect becomes more pronounced.
The direction of the Earth’s axis drifts somewhat throughout the course of one orbit around the sun. This means that the location of the solstice along our orbit changes by a very modest amount. The solstice occurs around 20 minutes before one full trip in front of the background stars!
Our drifting calendars
Because we base our calendar on the solstices and equinoxes (and astrologers on the signs), the Earth does not complete an orbit in a single year. The tropical or seasonal year is really a fraction of a second shorter than one full orbit (sidereal year). This means that the sun’s position in relation to the stars on any particular day varies throughout the year. For example, on June 21, a very small amount of snow falls.
However, after 2,000 years, the sun will be in a completely other constellation!
The sun was nearly halfway between Gemini and Cancer on the June solstice 2,000 years ago. The sun was between Gemini and Taurus on the June solstice fourteen years ago. In the year 4609, the June solstice point will move from Taurus to Aries, leaving Taurus behind.
When humanity formed the present Western zodiac some 2,000 years ago, the signs were roughly aligned with their respective constellations. However, the steady wobble of the Earth’s axis has led the solstice and equinox locations to shift around 30 degrees westward relative to the constellations in the intervening ages. Signs and constellations are currently around one calendar month off. They’ll be approximately two months away in another two thousand years or so.
Modern constellations and the zodiac
To make matters even more complicated, unlike astrological signs, constellations are not all the same size and shape. For the most part, the stars that make up a constellation are not physically related. They’re simply based on patterns that our forefathers noticed when they looked up at the sky, trying to make sense of it all.
The International Astronomical Union (IAU) established the constellations as sky regions, not only star patterns, in 1930. They established the boundaries we use today as a result of this. These current constellations are based on those introduced in the second century CE by Greek astronomer Ptolemy. He, in turn, took them from Babylonian scriptures dating back thousands of years. Throughout history, several societies have seen patterns in the sky that are unique to them. Some constellations are shared by many cultures (Orion is a good example), but not all.
There are actually 13 constellations that lay along the path of the sun, based on the present borders. Ophiuchus, the Serpent Bearer, sits between Sagittarius and Scorpius and is not mentioned in any horoscope. The signs stay stable in relation to the solstices and equinoxes, while the solstices and equinoxes shift westward in relation to the constellations or backdrop stars.
While the zodiac isn’t a fantastic predictor of love, fortune, or health, it is an excellent tool for better understanding the sun’s, Earth’s, and even the cultures that have come and gone on our small planet. The zodiac signs, which are drawn from constellations that line the path of the sun in the sky, trace Earth’s orbit and wobble and serve as a reminder of astronomy’s humble beginnings.
Bottom line: While you may identify the term zodiac with astrology, it also has a prestigious role in astronomy. The 12 constellations that make up the zodiac are located along the sun’s annual motion across the sky.

When it comes to inflatables, how long do they last?
You might ask how long your PVC inflatable boat will endure. The quality of the fabric, how seams are made, how it is cared for, and what atmosphere it is kept in are all things to consider. A well-maintained, high-quality inflatable can last anywhere from 5 to 10 years. Where they are used and how well they are cared for define this range. While PVC has greatly improved over time, UV deterioration is still a significant influence in the life of an inflatable. When PVC is exposed to UV radiation for an extended amount of time, the additives migrate to the surface and start to harm the glue. Heat and humidity, among other things, can put a lot of strain on the inflatable. However, it will be the glue that keeps the attachments, transom, and seams together that will fail first, not the cloth. While the cloth can be utilized after the adhesive has worn out, everything else that keeps the boat together and is affixed to it must be replaced. Replacing these pieces and making glue repairs can cost as much as the boat itself.
What took the place of Hypalon?
PVCor CSM/Hypalon fabric is used to make almost all inflatable boats. Hypalon was discontinued by its maker (DuPont) and is now supplied under the new name “CSM,” or Chlorosulfonated Polyethylene Rubber, which has a slightly different formula.
PVC or Orca CSM (Hypalon) from France are used to construct coastal boats.
Each cloth has its own set of benefits and drawbacks. When making your decision, keep both textiles in mind.
PVC fabric is recognized to be less expensive than CSM fabric.
PVC is quite sturdy and may be found in a variety of thicknesses, including.09mm and 1.2mm, but it still does not repel sunlight as well as CSM. It can certainly be preserved in excellent condition and last for a long time if properly cared for.
CSM, on the other hand, is more expensive in the long run but will last longer and is resistant to sun damage as well as gasoline spills and odors. CSM is simply more durable, more expensive, and has a great tolerance for a wide range of locations and weather conditions.
PVC Pros & Cons
- Pro: It’s a lot less pricey.
- PVC is lighter and more portable, which is a plus.
- Cons: UV resistance isn’t as good as it could be.
- Cons: Chemicals, gas, oil, and abrasion resistance aren’t as good.
- Shorter life cycle is a disadvantage. 8 to 10 years is the average life cycle.
CSM (Hypalon) Pros & Cons
- Pro: Excellent chemical resistance and UV-ray stability
- Heat, shock, and impact cause it to expand and flex.
- Pro: A 15-20-year life cycle is possible.
- Cons: Expensive when compared to PVC (100 percent to 150 percent more expensive)
- Cons: Due to its structure, it will lose air a little faster over time.
