Kawirikawiri, pali kusiyana kwakukulu pakati pa silicone yodziwika bwino ndi silicone yodziwika bwino pankhani ya mtengo ndi mtengo. Silicone yodziwika bwino ili ndi mtengo ndi mtengo wokwera chifukwa cha miyezo yake yokhwima yachitetezo komanso zofunikira zapamwamba; pomwe silicone yodziwika bwino ili ndi ubwino wina pamitengo ya zinthu zopangira ndi njira zopangira, ndipo mtengo wake ndi wotsika, koma imagwira ntchito bwino pakuchita bwino kwa chilengedwe komanso mphamvu zakuthupi ndi zamakemikolo, ndipo imakhala ndi mtengo wokwera kwambiri.

Chidule
Ngakhale kuti silicone yodziwika bwino komanso silicone yoteteza chilengedwe ndi zinthu zopangidwa ndi silicone, pali kusiyana kwakukulu m'mbali zambiri.
Kuchokera ku tanthauzo ndi miyezo, silicone ya chakudya imagwiritsidwa ntchito makamaka m'magawo okhudzana ndi chakudya ndipo iyenera kukwaniritsa miyezo yokhwima yadziko lonse komanso ziphaso zapadziko lonse lapansi, monga China GB 4806.11-2016, US FDA 21 CFR 177.2600, EU LFGB, ndi zina zotero. Ili ndi zofunikira kwambiri pakuyera kwa zinthu zopangira, kuwongolera njira zopangira komanso chitetezo cha zinthu zomaliza. Silicone yosamalira chilengedwe imayang'ana kwambiri kuchetsa chilengedwe popanga, kugwiritsa ntchito ndi kuyeretsa zinyalala, ndipo imagwirizana ndi miyezo ya chilengedwe monga EU RoHS Directive ndi REACH regulations.
Ponena za zipangizo zopangira ndi njira zopangira, silicone yapamwamba ya chakudya imagwiritsa ntchito mchenga wa silica kapena quartz woyeretsedwa kwambiri, imapangidwa m'malo ochitira zinthu oyera, imagwiritsa ntchito platinum vulcanizer, ndipo imayesedwa bwino kwambiri panthawi yonseyi. Zinthu zopangira silicone zomwe siziwononga chilengedwe zimapezeka kwambiri, mphamvu zoyera zimagwiritsidwa ntchito popanga, madzi otayira ndi mpweya wotulutsa utsi zimatsukidwa mosamala, ndipo zinyalala zimabwezeretsedwanso.
Ponena za chitetezo ndi thanzi, silicone yapamwamba ya chakudya siili ndi poizoni komanso yoopsa, imakhala ndi kutentha kwambiri, ndipo zizindikiro monga kuchuluka kwa zitsulo zolemera zimakwaniritsa miyezo yowonetsetsa kuti chakudya chili bwino. Kupanga ndi kugwiritsa ntchito silicone yoteteza chilengedwe sikuwononga kwambiri, ndipo zinyalala zimatha kubwezeretsedwanso ndikugwiritsidwanso ntchito. Kugwiritsa ntchito kwabwinobwino sikukhudza thanzi la anthu.
Ponena za makhalidwe ake enieni komanso a mankhwala, silicone yapamwamba pa chakudya imakhala ndi kukana kutentha kwambiri, kukalamba komanso kulephera kung'ambika, ndipo ndi yoyenera kutentha kwambiri komanso kugwiritsidwa ntchito kwa nthawi yayitali. Silicone yosamalira chilengedwe imakhala yolimba bwino, imatha kubwezeretsedwanso ndikugwiritsidwanso ntchito, imakhala ndi kukhazikika kwa mankhwala ambiri, ndipo imatha kuthana ndi malo ovuta a mankhwala.
Ponena za malo ogwiritsira ntchito, silicone yodziwika bwino imagwiritsidwa ntchito kwambiri m'magawo azakudya ndi azachipatala, monga ziwiya zakukhitchini, ma CD a chakudya, zinthu za ana, zida zamankhwala, ndi zina zotero. Silicone yoyera chilengedwe imagwiritsidwa ntchito kwambiri m'magawo amafakitale ndi omanga, monga zida zamagetsi, kupanga makina, ndege ndi asilikali, kutseka nyumba ndi kukongoletsa, ndi zina zotero.
Ponena za mtengo ndi mtengo, silikoni ya chakudya ndi yokwera mtengo chifukwa cha zofunikira zambiri kuti zinthu zopangira zikhale zoyera, kuwongolera kwambiri kupanga, komanso mtengo wapamwamba wowunikira komanso kupereka satifiketi. Silikoni yosamalira chilengedwe ili ndi mtengo wotsika wa zinthu zopangira, njira yopangira yosasunthika, komanso mtengo wotsika mtengo.

Mwachidule, silicone yodziwika bwino ndi yodziwika bwino ndi chilengedwe ili ndi makhalidwe awoawo ndipo ndi yoyenera m'magawo osiyanasiyana. Silicone yodziwika bwino ndi chakudya imaonedwa kuti ndi yotetezeka ndipo ndi yoyenera m'malo omwe ali ndi zofunikira kwambiri paumoyo monga chakudya ndi chithandizo chamankhwala; silicone yodziwika bwino ndi chilengedwe ili ndi magwiridwe antchito abwino kwambiri pachilengedwe ndipo ndi yoyenera m'magawo monga mafakitale ndi zomangamanga zomwe zimaganizira kwambiri za kuwononga chilengedwe.
