✦ Synopsis

Polyethylene greenhouse foils show an extraordinary prolonged lifetime at exposure to natural and artificial weathering if a gas-phase fluorination under low-pressure conditions was applied. The fluorination was performed by F 2 /N 2 mixtures and provided ca. 50 F/100 C (fluorination degree % 25%). The lifetime of PE greenhouse foils at exposure to artificial or natural weathering were increased by at least the factor 2 ± 4 measured in terms of tensile strength and break at elongation.
