There are several factors that cause metals to rust, but "the rust on that metal may be caused by corrosive gases." When it comes to corrosive gases, one might think of volcanic gases produced in sulfur hot springs or exhaust gases from cars and forklifts. However, there are actually sources nearby that can generate reducing sulfur as well, such as paper, cardboard, wood, packaging materials, rubber, and lubricants. Everyday packaging materials can also be affected by corrosive gases that cause rust. Therefore, simply storing electronic components and automotive parts puts them at risk of rusting. To reduce the impact of rust caused by corrosive gases and to protect metals and resins from rust, "sulfur gas adsorption sheets" are suitable. With sulfur gas adsorption sheets, you can use them even for electronic components and semiconductors where vapor-phase rust prevention paper cannot be used. ◆ We are currently offering a document that clearly outlines rust prevention measures for various metals. ◆ * For more details, please download the document or feel free to contact us.
