Available as roll stock, ELASTOSIL® Film is made, in cleanroom conditions and without use of solvents, entirely from silicone elastomers and comes in thicknesses down to 20 microns. Intermediate backing allows film to be peeled off intact, and film thickness across entire width and length of film web deviates from specification by ±5% at most. Film is permeable to water vapor and certain gases, such as oxygen, nitrogen, and carbon dioxide but not to water.
