Iimpawu ezigqwesileyo zomzimba kunye noomatshini:Emva kwe-vulcanization, inamandla aphezulu kakhulu okuqina, amandla okukrazula, ukuxhathisa kunye nokomelela.
Ukumelana okugqwesileyo kumaqondo obushushu aphezulu naphantsi:Ubude bexesha elide-uluhlu lwamaqondo obushushu okusebenza luqhelekile ukusuka ku -60℃ukuya +200 isidanga okanye nangaphezulu (iifomula ezikhethekileyo zinokufikelela ngaphezulu kwe 250℃), kwaye inokumelana namaqondo obushushu aphezulu okanye asezantsi ixeshana elifutshane.
Ukumelana nemozulu okubalaseleyo kunye nokumelana ne-ozone:Ukuchasana okugqwesileyo kwe-UV kunye nokumelana nokuguga, kunye nobomi benkonzo ende.
Ukusebenza okugqwesileyo kokufakelwa kombane:Izinzile ngaphakathi koluhlu olubanzi lobushushu kunye noluhlu lwamaza.
Uzinzo olululo lwekhemikhali:ukumelana namanzi, i-oxidation, kunye neekhemikhali ezahlukeneyo (kodwa nge-avareji ye-solvent resistance).
Ukungazinzi ngokwasemzimbeni:Iyahambelana nemigangatho yokutya kunye nebakala lezonyango (ifomula ekhethekileyo kunye nesiqinisekiso siyafuneka).
Ukucaca okuphezulu:Ingenziwa kwiimveliso ezicace kakhulu.
