Abstract: Disclosed herein are polyurethane foams which can be used for reducing or preventing the corrosion of polymeric materials, which can be produced by mixing components (a) at least one polyisocyanate, (b) at least one compound having at least two groups reactive toward isocyanates, (c) optionally chain extender and/or crosslinking agent, (d) blowing agent, (e) catalyst, (f) optionally auxiliaries and additives, and (g) at least one anhydride to give a reaction mixture, and curing said reaction mixture to give the polyurethane foams, where the anhydride is added in an amount of 0.05-5 wt %, based on the weight of component (a). Also disclosed herein are a method of reducing or preventing the corrosion of polymeric materials by using such polyurethane foams and a method of using the polyurethane foams in certain applications, for example, in automotive interiors.

Abstract: A production device for a fuel tank, having two or more built-in components attached to an inside of a fuel tank body when the fuel tank body is formed, includes: jigs configured to have the built-in components placed thereon; and a feed robot, as a feed device, configured to feed the built-in components, along with the jigs having the built-in components placed thereon, to a position below molding dies. The feed device may feed the jig, having the built-in components placed thereon, to the position via a subsurface feed path leading to the position.
