Product Description

                                                 DERFLEX Urethane material for Raft and Boat Urethane fabric


Urethane material for Raft and Boat:
Polyurethane, commonly abbreviated PU. Polyurethanes are in the class of compounds called reaction polymers, which include epoxies, unsaturated polyesters, and phenolics.
100% Polyurethane material offers four times the abrasion resistance and greater tear or tensile strength compared to Hypalon and much stronger than PVC.
Polyurethane fabrics have excellent welding properties. Both hot air/pressure rotary Welders and Radio Frequency Welders can be used to join the material together in a molten state, thereby creating an incredibly strong bond.
The combination of the elastomeric properties of Urethane and the resiliency properties of nylon allows the material to repeatedly stretch and still recover to show its original properties.
Polyurethane was originally manufactured in the early 70's as fuel cell bladders for helicopter fuel for different use and has proved to be the ideal material for boat pontoons.

VII: Urethane material Raft Advantages and Disadvantages:
Advantages: Slips nicely over rocks, most durable fabric, lightweight, best puncture and tear resistance, durable. The welding process they use to make these boats is bomber.
Polyurethane has an incredibly long lifetime.
Resist mechanically wear and tear very well.
The latest polyurethane fabrics shows an excellent resistance when exposed to sunlight (UV) and chemicals - even better than Hypalon.
Polyurethane is the strongest air-holding material available.
Easy to repair.
Polyurethane is less damaging to the environment
Contains NO chlorine
Demanding to use in production.
Polyurethane is the best material for pontoons and is recommended for professional boats.
Disadvantages: Fairly expensive, tough to roll and transport, difficult to field repair.
