Segondè pèmeyabilite ki gaz: nan tanperati chanm (25 ° C), pèmeyabilite ki nan kawotchou silicone pou gaz tankou oksijèn se apeprè 400 fwa [sitasyon bezwen] sa yo ki an kawotchou BUTYL, fè silicone itil pou aplikasyon pou medikal nan ki ogmante se aere vle. Kontrèman, gom silicone pa kapab itilize kote gaz-sere sele ki nesesè.

High gas permeability: at room temperature (25 °C), the permeability of silicone rubber for such gases as oxygen is approximately 400 times[citation needed] that of butyl rubber, making silicone useful for medical applications in which increased aeration is desired. Conversely, silicone rubbers cannot be used where gas-tight seals are necessary.
