Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.
Apollo alkaline fuel cell Alkaline fuel cells played a key part in the success of the 1960s U.S. Space Program that put a man on the moon for the first time.
