It's PVC...suggest getting Hypalon if you want long life. (Duratex is a fancy name for PVC impregnated fabric)
QUOTE from Mercury:
1100 DURATEX —- Inflatables constructed with 1100 Duratex fabric are durable, look great and are a perfect choice for casual, recreational use. We build these boats to endure hard use and back them with a five-year limited warranty on both the fabric and seams.
HYPALON —- Our boats are made with top-quality Hypalon neoprene-coated fabric are the choice for more demanding use. They are extremely durable and highly resistant to ultraviolet light, chemicals, gas, and oils. They’ll even remain flexible in extreme cold or hot temperatures. It is not uncommon for a properly maintained boat to last well beyond its warranty, which is why they have a premium warranty coverage of ten years on fabric and seams.
