Product Description

                                           Derflex PVC Coated Fabric for Raft polyester material for Raft           


Polyvinyl chloride, commonly abbreviated PVC, is a widely used thermoplastic polymer. PVC can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. In this form, it is used in clothing and upholstery, and to make flexible hoses, tubing and of cause pontoons.
The plasticizer in PVC has the great disadvantage that it in time (and especially when exposed to UV-radiation) decomposes and leaves the pontoon fabric hard, crisp, and mechanically much weakened. Stories of pontoons that 'rotten in the sun' are stories of old PVC pontoons exposed to sun.
Fabrics made by PVC are hard to joint, you can only use a single cure adhesive, which is PU ester. Some manufacturers use high mechanical pressure, high frequency welding or electronically welding, which makes mass production of boats possible in a large scale with machinery and inexperienced labour.
PVC fabrics are produced in a larger palette of colors than fabrics made of Hypalon and Polyurethane. PVC is considered the poorest material for pontoon production and is mainly used in cheap mass-produced boats.


PVC Raft material advantages and disadvantage:

Advanatges: inexpensive. The production of PVC fabric is easier than when using both Hypalon® or Polyurethane.
Less Expensive
Stiffer material
Less flex in the boat in the boat in harder whitewater
Often have drop stitched floors which is great for standing and casting when angling
Disadvantages:
not particularly durable, can crack when rolled in cold temperatures, tend to be mass produced so these boats are known for quality issues.
A cheaper material than Hypalon and Polyurethane has a short lifetime when exposed to sunlight (UV).
Contains chlorine
The strength and the ability to resist tear and wear is radically poorer than that of Hypalon® or Polyurethane.
