ABSTRACT:
A polyurethane reinforced fabric molded flexible fuel tank comprises a high molecular weight thermoplastic polyurethane polymer binder melt applied to reinforcing fabric and molded into a flexible fuel tank or container for storage of gasoline or jet fuels. The polyurethane polymer has an average molecular weight from about 60,000 to about 500,000 and particularly exhibits excellent fuel resistance.
The high molecular weight thermoplastic polyurethane comprises the polymeric reaction product of an ethylene ether oligomer glycol intermediate co-reacted with a non-hindered diisocyanate and an extender glycol to produce the polyurethane polymer. The ethylene ether oligomer glycol intermediate is selected from (a) a diethylene glycol-aliphatic linear polyester or (b) a polyethylene glycol. The oligomer glycol intermediate has an average molecular weight from about 500 to about 5,000.
