Yinto enye, uhlobo lwezoqoqosho kunye nokusebenza kakuhle kwePolyurethane foam. Ifakwe ngentloko ye-adapter yeplastiki ukuze isetyenziswe ngompu wesicelo se-foam okanye i-straw. I-foam iya kwanda kwaye inyange ngokufuma emoyeni. Isetyenziselwa uluhlu olubanzi lwezicelo zokwakha. Kulunge kakhulu ukugcwalisa kunye nokutywinwa ngobuchule obugqwesileyo bokuxhoma, i-thermal ephezulu kunye ne-acoustical insulation. Iyahambelana nokusingqongileyo njengoko ingenayo nayiphi na imathiriyeli yeCFC. Ifomula yokushisa ephantsi, ilungele ukusetyenziswa ebusika.
