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.
High igesi permeability: ekamelweni lokushisa (25 ° C), i-permeability ka abicah enjoloba amagesi njengomoya-mpilo cishe izikhathi ezingu-400 [ukulandisa ezidingekayo] ukuthi we butyl iraba, okwenza abicah wusizo izicelo bezokwelapha lapho lenyuka aeration okunxanelekayo.
