Irabha ye-silicone ye-methylphenylvinyl iwumkhiqizo otholwe ngokwethula amayunithi e-methylphenylsiloxane noma amayunithi e-diphenylsiloxane ochungechungeni lwamangqamuzana erabha ye-methylvinyl silicone. Ukusebenza kwayo kanye nezinkambu zokusetshenziswa kwayo kusazoqhutshekwa kufundwe futhi kuhlolwe.
Ukwethula amaqembu e-phenyl emaqenjini aseceleni e-polysiloxane kuzophazamisa ukujwayela kwesakhiwo se-dimethylsiloxane, ngaleyo ndlela kwehlise ngokuphawulekayo izinga lokushisa lekristalu le-polymer futhi kunwetshwe ngokuqhubekayo ububanzi bayo besicelo{0}}sezinga lokushisa eliphansi. Ngakho-ke, irabha ye-silicone ye-methyl phenyl vinyl ayitholi nje kuphela izinzuzo eziningi zenjoloba ye-methyl vinyl silicone, njengesethi encane yokuminyanisa, ububanzi bokushisa okusebenzayo, ukumelana ne-oxidation, ukumelana nesimo sezulu, ukumuncwa ukushaqeka, ukumelana nomswakama kanye nokufakwa kahle kukagesi, kodwa futhi ibonisa ukumelana{2}}nokushisa okuphakeme okuvelele, ukumelana nokukhipha umoya kanye nokumelana nemisebe.
Lezi zakhiwo zizohluka ngokuqukethwe okuhlukile kwe-phenyl kuchungechunge lwamangqamuzana. Uma okuqukethwe kwe-phenyl kuphakathi kuka-5% no-10%, le rabha ye-silicone ibizwa ngokuthi-irabha ye-phenyl silicone ephansi. Inokumelana nokubanda okuhle kakhulu futhi ingagcina ukunwebeka kwenjoloba emazingeni okushisa asukela -ku-70 ukuya -ku-100℃, okuyenza ibe enye yamarabha anokusebenza{14}}okusezingeni eliphezulu okuphansi kakhulu. Khonamanjalo, izindleko zayo zisesilinganisweni futhi kulindeleke ukuthi kuthathelwe indawo irabha ye-silicone ye-methyl vinyl. Uma okuqukethwe kwe-phenyl kufinyelela ku-20 kuya ku-40%, kubizwa ngokuthi irabha ye-phenyl silicone ephakathi. Ayigcini nje ngokukwazi ukumelana nelangabi kodwa futhi ikwazi ukuzicisha uma ivutha. Lapho okuqukethwe kwe-phenyl kuthuthukiswa futhi kufinyelele ku-40-50%, kwakheka irabha ye-silicone ye-phenyl ephezulu, enokumelana okuhle kakhulu emisebeni futhi ekwazi ukumelana nemisebe ye-gamma ephakeme njengo-1xI08 rontgen. Sekukonke, njengoba okuqukethwe kwamaqembu e-phenyl kwanda, ukuqina kweketango lamangqamuzana enjoloba ye-silicone kuyaqina kancane kancane, futhi ukumelana kwayo nezinga lokushisa eliphansi kuncipha kancane kancane. Kodwa-ke, ngesikhathi esifanayo, ukuvinjelwa kwelangabi kanye nokumelana nemisebe yenjoloba ene-vulcanized kuye kwathuthukiswa kakhulu.
