O2 plasma treatment shows the opposite temperature dependence compared to Ar plasma treatment!
We would like to introduce the technical data regarding the temperature dependence of discoloration for heat-resistant label No. 102 (low sensitivity type). In Ar plasma treatment, the color difference ΔE*ab tends to decrease with higher temperature conditions. In O2 plasma treatment, the color difference ΔE*ab tends to increase with higher temperature conditions, showing a temperature dependence opposite to that of Ar plasma treatment. 【Overview of Ar Plasma Treatment】 ■ RF plasma device (manufactured by Arios Co., Ltd.) ■ RF power: 60W ■ Ar gas flow rate: 40 sccm ■ Achieved vacuum level: 5×10^-4 Pa ■ Treatment pressure: 10 Pa ■ Stage temperature: 25–200℃ 【Overview of O2 Plasma Treatment】 ■ RF plasma device (manufactured by Arios Co., Ltd.) ■ RF power: 60W ■ O2 gas flow rate: 40 sccm ■ Achieved vacuum level: 5×10^-4 Pa ■ Treatment pressure: 10 Pa ■ Stage temperature: 25–200℃ *For more details, please refer to the related links or feel free to contact us.
