Ukwanda kwe-oyile ekrwada kwihlabathi liphela kutshanje kuchaphazele icandelo leekhemikhali, nto leyo enyusa iindleko zokwakha imveliso yokwenziwa. Ekubeni i-crude isisiseko sezinto ezifana ne-butadiene kunye ne-acrylonitrile—ezibalulekileyo kwimveliso yeNitrile Rubber (NBR)—abavelisi baziva becinezelwe kakhulu.
Ababoneleli sele beqalile ukulungisa amaxabiso esivumelwano ukuze banciphise iindleko zokutya okuphezulu. Ukuba ioyile ihlala kula manqanaba, kusenokwenzeka ukuba sibone ukuncipha kobonelelo kwiirabha ezithile zokwenziwa, eziya kunyusa amaxabiso kuphela. Esi siphumo sifika ngqo kwikhonkco lobonelelo lweglavu olusezantsi, nto leyo eshiya abavelisi bengenakukhetha ngaphandle kokuphinda bacinge ngamaqhinga abo okubeka amaxabiso ukuba le ndlela iyaqhubeka kwikota elandelayo.
