FUNSOR inflatable products are made of 1,100 Dtex (0.9mm) or 1550 Dtex the (1.2mm) New Generation PVC fabric with polyester support, having excellent resistance to tearing, tension and breaking.
All boats are hand-sealed at the seams for perfect seaming, the most expensive and reliable method used today. Each seam is strengthened with four layers of bonded fabric for maximum strength and durability. The seams are virtually indestructible and will not fall apart, even after many years of use in any weather. All seams are quadruple overlap for better protection as shown below:
There are currently two major methods constructing an inflatable boat: welded and glued seams. And there is a lot of misunderstanding about “glued” PVC vs. "welded". In fact, “glued” PVC is actually solvent-welded, whereas “welded” PVC is heat-welded, and both methods result in a similar fusing of the membrane. Also, “welded” PVC may be more susceptible to damage from folding than “glued” PVC. Furthermore, the four layer bonding construction used by FUNSOR actually provides more overlay and reinforcement of the seam than the simple overlap of welded construction of welding.
Glued seams on a PVC boat are fundamentally different than glued seams on a rubber (Hypalon/Neoprene) boat.
Hand Glued Seams Vs. Welded Seams
Glued (PVC)
Strength/Bond type: Strong -- Chemical/Molecular bond
Durability: Good -- Problems with old PVC boats falling apart have been resolved for over 10 years.
Welded (PVC/Polyurethane)
Strength/Bond type: Strong -- Molecular bond
Durability: If temperature, feed rate, and other factors are ideal: Good. -- Welding combined with folding a boat can cause microscopic fracturing of the coating resulting in the boat loosing air over time. Welded seams are not advisable with polyester base fabrics.
