ʻO ka methylphenylvinyl silicone rubber he huahana i loaʻa ma ka hoʻokomo ʻana i nā ʻāpana methylphenylsiloxane a i ʻole nā ʻāpana diphenylsiloxane i loko o ke kaulahao mole o ka methylvinyl silicone rubber. E aʻo hou ʻia a ʻimi ʻia kāna mau hana a me nā kahua noi.
ʻO ka hoʻokomo ʻana i nā pūʻulu phenyl i nā pūʻulu ʻaoʻao o polysiloxane e hoʻopau i ka maʻamau o ke ʻano o ka dimethylsiloxane, ma laila e hōʻemi nui ai i ka mahana crystallization o ka polymer a e hoʻonui hou i kona ʻano haʻahaʻa haʻahaʻa haʻahaʻa. No laila, methyl phenyl vinyl silicone rubber 'aʻole wale i hoʻoili i nā pono he nui o ka methyl vinyl silicone rubber, e like me ka liʻiliʻi compression set, wide operating temperature range, oxidation resistance, weather resistance, shock absorption, moisture resistance and good electrical insulation, akā, e hōʻike ana hoʻi i ke kūʻokoʻa haʻahaʻa haʻahaʻa, ablation resistance a me radiation resistance.
E ʻokoʻa kēia mau waiwai me ka ʻokoʻa o ka phenyl i loko o ke kaulahao molekala. Aia ka ma'i'o phenyl ma waena o 5% a me 10%, ua kapa 'ia kēia 'opa'a silikoni ha'aha'a-pāpa'a silicone ha'aha'a. He kūpaʻa anuanu maikaʻi loa kona a hiki ke mālama i ka elasticity lāʻau lapaʻau ma nā mahana mai -70 a i -100 degere, e lilo ana ia i hoʻokahi o nā ʻōpala me ka hana haʻahaʻa haʻahaʻa maikaʻi loa. I kēia manawa, he haʻahaʻa kona kumukūʻai a manaʻo ʻia e hoʻololi i ka methyl vinyl silicone rubber. Inā hiki i ka 20 a hiki i ka 40% ka maʻiʻo phenyl, ua kapa ʻia ʻo ia ka ʻea -phenyl silicone rubber. ʻAʻole wale ia he pale ahi maikaʻi loa akā hiki ke hoʻopau iā ia iho i ke ahi. Ke hoʻonui hou ʻia ka maʻiʻo phenyl i 40-50%, ua hoʻokumu ʻia ka phenyl silicone rubber kiʻekiʻe, nona ke kūpaʻa radiation maikaʻi loa a hiki ke kū i nā kukuna gamma kiʻekiʻe e like me 1xI08 rontgen. Ma keʻano holoʻokoʻa, e like me ka piʻi ʻana o nā pūʻulu phenyl, ʻoi aku ka ikaika o ka rigidity o ke kaulahao mole o ka silicone rubber, a me ka haʻahaʻa haʻahaʻa haʻahaʻa e emi iho ana. Eia nō naʻe, i ka manawa like, ua hoʻomaikaʻi maikaʻi ʻia ka pale ʻana o ka lapalapa a me ka pale ʻana i ka radiation o ka vulcanized rubber.
