WebClass II vapor retarder: 0.1 < perm <1.0 perm. Class III vapor retarder: 1.0 < perm <10 per m. * The desiccant testing method specifies that testing is conducted at a 25% relative humidity or RH. Watch out: builders and building diagnosticians note that indoor relative humidity levels are normally well above 25% RH. WebWhen exposed to environmental moisture, most high-performance semiconductor organic compounds built on plastic substrate show degraded performance [11,174].This requires the plastic substrate to have low water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) features. For OLED, WVTR, and OTR of the substrates are …
