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.
Permeability gaaska High: heerkulka qolka (25 ° C), permeability ee caag silicone for gaasas sida oxygen waa qiyaastii 400 jeer [yeerida loo baahan yahay] in caag butyl, samaynta silicone waxtar u leh codsiyada caafimaad, taas oo kor u tuulista la doonayo.
