High gas permeability: At room temperature (25 °C), the permeability of silicone rubber for such gases as oxygen is approximately 400 times 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.
