Resin mai ƙaramin ƙarfi (nau'in XJ): Ana amfani da shi galibi don sauran samfuran filastik.
3. Muhimman Abubuwan PVC
(1) Halayen Rufe Wutar Lantarki: A matsayin kayan dielectric mai ƙarfi sosai, resin PVC yana nuna kyawawan halaye na rufi na lantarki amma kaɗan ƙasa da haka idan aka kwatanta da kayan da ba na polar ba kamar polyethylene (PE) da polypropylene (PP). Juriyar girma ta wuce 10¹⁵ Ω·cm; a mita 25°C da 50Hz, ma'aunin dielectric (ε) yana tsakanin 3.4 zuwa 3.6, yana bambanta sosai tare da canje-canjen zafin jiki da mita; ma'aunin wargajewa (tanδ) yana tsakanin 0.006 zuwa 0.2. Ƙarfin rushewa ya kasance mai girma a zafin ɗaki da mitar wutar lantarki, ba ya shafar polarity. Duk da haka, saboda asarar dielectric mai yawa, PVC bai dace da aikace-aikacen babban ƙarfin lantarki da mita mai yawa ba, ana amfani da shi azaman kayan rufi don ƙananan da matsakaicin ƙarfin lantarki ƙasa da 15kV.
(2) Kwanciyar Hankali: Duk da cewa tsarin kwayoyin halitta yana nuna kyakkyawan kwanciyar hankali na tsufa saboda haɗin chlorine-carbon, PVC yana yawan sakin hydrogen chloride yayin sarrafawa a ƙarƙashin matsin lamba na zafi da na inji. Iskar oxygen tana haifar da lalacewa ko haɗin gwiwa, yana haifar da canza launi, embrittle, raguwar ƙa'idodin injina, da kuma lalacewar aikin kariya na lantarki. Saboda haka, dole ne a ƙara masu daidaita daidaito masu dacewa don inganta juriya ga tsufa.
(3)Halayen Thermomechanical: A matsayin polymer mara tsari, PVC yana wanzuwa a cikin yanayi uku na zahiri a yanayin zafi daban-daban: yanayin gilashi, yanayin jurewa mai yawa, da yanayin kwararar ruwa mai kauri. Tare da zafin canjin gilashi (Tg) kusan 80°C da zafin kwarara kusan 160°C, PVC a yanayin gilashinsa a yanayin zafin ɗaki ba zai iya biyan buƙatun aikace-aikacen waya da kebul ba. Gyara ya zama dole don cimma mafi girman sassauci a zafin ɗaki yayin da yake kiyaye isasshen juriya ga zafi da sanyi. Ƙara masu filastik na iya daidaita zafin canjin gilashi yadda ya kamata.
