CAIRO, June 5 (Reuters) - Several Egyptian chemical and fertilizers companies have preventively shut down their factories on a temporary basis, citing increased consumption-driven pressures on the natural gas network leading to fluctuations in the grid.

Egypt Kuwait Holding (EKH), Misr Fertilizers Company (MoPCO), and Abu Qir Fertilizers and Chemical Industries said they will shut down for 24 hours until network pressure stabilizes, while Egyptian Chemical Industries Corp (KIMA), Sidi Kerir Petrochemicals Co. have not given a timeline for the closure.
