HIGH-PRESSURE GAS HOSE OR STORAGE VESSEL |
摘要 |
Disclosed is a high-pressure gas hose or storage vessel comprising at least one layer of a resin composition comprising (A) 1,2-diol in a side chain-containing vinyl alcohol-based resin, and (B) fluororesin having polar functional group capable of reacting with or forming hydrogen bond(s) with hydroxyl group. The gas-barrier layer comprising the resin composition has a favorable wettability of the interface between the component (A) and the component (B), and therefore the gas-barrier layer exhibits high level gas-barrier property without causing blister under the condition of high pressure of not only oxygen or air but also small molecule gas such as hydrogen. Furthermore, the gas barrier layer has superior flexibility and superior durability with respect to changes accompanying the supply and removal of high-pressure gas. |
