Inflatable kayaks have evolved significantly over the past few decades, becoming a viable option for water enthusiasts worldwide. From beginners to seasoned paddlers, everyone is hopping onto the inflatable kayak trend. Among the different materials used in their construction, PVC (polyvinic chloride) has emerged as a popular choice. But what exactly are PVC inflatable kayaks made of? Let’s dive deeper into the composition, production, and durability of these marvels of modern watercraft engineering.
PVC: The Heart of Inflatable Kayaks
PVC or polyvinyl chloride is a type of plastic distinguished by its durability, flexibility, and relative affordability. This material is a blend of 57% chlorine (derived from industrial grade salt) and 43% carbon (derived predominantly from oil/gas via ethylene). These characteristics make PVC an ideal material for creating sturdy, versatile inflatable kayaks.
Manufacturing Process: The Transformation into a Kayak
How does PVC transform from a raw material into a robust inflatable kayak? The process is quite fascinating. Initially, PVC comes in a powdered form, which is then combined with several other substances such as plasticizers for flexibility, stabilizers for resistance to heat and light, and pigments for color.
This mixture is then subjected to heat, converting it into a malleable state that can be molded into the desired form. When it comes to inflatable kayaks, the PVC is typically formed into layers that are used to construct the kayak’s body.
The layers of PVC are then joined together using a process called ‘welding’. There are two common types of welding used in inflatable kayak manufacturing, namely radio frequency (RF) welding and hot air welding.
RF welding uses electromagnetic energy to heat and fuse the PVC materials. On the other hand, hot air welding involves forcing hot air between two overlapped pieces of material and applying pressure for the fusion. The result of these processes is airtight and waterproof seams that ensure the kayak’s buoyancy and structural integrity.
Multiple Layers: The Secret to Durability
A standout feature of PVC inflatable kayaks is their multilayer construction. Typically, these kayaks consist of three separate layers. The outer layer is UV-resistant and adds a first level of defense against punctures and abrasions. The middle layer is a fabric mesh, usually of polyester or nylon, which provides structural strength and rigidity. The inner layer is another PVC coating, making the kayak air and water-tight.
This layered construction provides a balance of flexibility and rigidity, ensuring that the kayak is durable enough to withstand challenging conditions, but flexible enough to be inflated and deflated without causing structural damage.
Durability and Maintenance
Despite their inherent strength and durability, PVC inflatable kayaks do require proper maintenance to ensure longevity. Regular cleaning, avoiding prolonged exposure to direct sunlight, protecting from sharp objects, and proper storage can significantly extend the lifespan of a PVC inflatable kayak.
Moreover, PVC is a repair-friendly material. Small punctures or leaks can often be fixed with a patch kit that usually comes with the kayak. For more significant damage, professional repair services are typically able to restore the kayak to a usable condition.
In Conclusion
In essence, the popularity of PVC inflatable kayaks lies in their durable, flexible, and lightweight nature, all thanks to their unique construction and the properties of PVC. They offer the convenience of easy transport and storage without sacrificing on performance. With proper care, they can serve as an excellent vessel for your water adventures for many years to come. While they might not entirely replace traditional hard-shell kayaks, they have undoubtedly carved out their niche in the world of water sports.
