kutentha stabilizer (PVC) ndi ma polima ena okhala ndi klorini. Methyl tin stabilizer ndi amorphous high polymer. Chifukwa cha kapangidwe kapadera ka PVC, kamene kadzawonongeka pa kutentha kwa kutentha, kupangitsa mtundu kukhala mdima, kuchepetsa thupi ndi makina, komanso kutaya mtengo wogwiritsira ntchito. Ma stabilizers otentha amapangidwa ndikupangidwa kuti athetse vutoli. Malinga ndi mitundu yosiyanasiyana yamankhwala, zowongolera kutentha zimagawidwa kukhala mchere wamchere, sopo wachitsulo, malata achilengedwe, dziko lapansi losowa, organic antimony ndi organic stabilizers. Mitundu yosiyanasiyana yazinthu imakhala ndi machitidwe awoawo ndipo ndi yoyenera kumadera osiyanasiyana. M'zaka zaposachedwa, makampani a PVC adakula mofulumira, zomwe zachititsa kuti pakhale chitukuko chofulumira cha mafakitale oletsa kutentha. Kumbali imodzi, chiphunzitso cha kutentha stabilizers chikukhala changwiro, chomwe chimapereka mikhalidwe yopezera zinthu zabwino kwambiri za PVC; Komano, zinthu zatsopano zoyenera madera osiyanasiyana zikupangidwa nthawi zonse, makamaka chifukwa cha poizoni wa mchere wamchere ndi zitsulo zolemera. Chifukwa chake ndikuti mabizinesi opangira ma PVC amayamba kusankha zolimbitsa thupi zopanda poizoni.
Pakupanga PVC mabizinesi processing, kuwonjezera pa amafuna kutentha stabilizers kukumana bata matenthedwe, iwo nthawi zambiri chofunika kuti processing wabwino, kukana nyengo, colorability koyamba, kukhazikika kuwala, ndi zofunika okhwima fungo lawo ndi mamasukidwe akayendedwe. Pa nthawi yomweyo, pali mitundu yambiri ya mankhwala PVC, kuphatikizapo mapepala, mapaipi, mbiri, kuwombera akamaumba, jekeseni akamaumba, thovu mankhwala, phala resins, etc. mabizinesi okha. Chifukwa chake, kusankha zowongolera kutentha panthawi ya PVC ndikofunikira kwambiri. Organotin heat stabilizers ndi zowongolera kutentha zomwe zapezeka mpaka pano
