摘要: The present invention relates to thermoplastic hollow vessels, tanks, drums and other industrially applicable housings. The invention is adaptable as plastic fuel tanks with low fuel permeability, e.g., less than 5 g.·mm/m2 day as a mono-layer structure. These vessels exhibit good sub 0 0C impact properties and are formed by relatively inexpensive blow molding or rotomolding processes. Disclosed are mono-layered hollow vessels comprising an uncompatibilized, fused blend composition of polyoxymethylene, thermoplastic polyurethane and a copolyester. In one embodiment mono-layered hollow vessels comprise uncompatibilized, fused polyoxymethylene, thermoplastic polyurethane and copolyester in the respective wt. amounts of 100, 5-15 and 5-15. According to a more preferred aspect the wt. ratio of thermoplastic polyurethane to copolyester is from 1:3 to 3:1.
