ptfe low-temperature plasma surface treatment film

our company's low-temperature plasma surface treatment equipment would deal with as roll unit PTFE film with width of 1500mm, roll diameter of 500mm and thickness of 0.025 0.5mm. After treatment by equipment, PTFE film surface energy would increase from 19dyns/cm up to 72dyns/cm, and it would also long-term maintain above 38dyns/cm, in the same time the outlook and each performance are without any effect.
