PVC SG-8
PVC SG-8
na USB ducts albarkatun kasa, PVC SG-8 da aka yi amfani da shi don samar da bangarori na bango,
Thermoplastic high-molecular polymer wanda aka yi ta hanyar dakatarwar polymerization na vinyl chloride monomer.Tsarin kwayoyin halitta: - (CH2 - CHCl) n - (N: digiri na polymerization, N= 590 ~ 1500).Shi ne danyen da aka fi amfani da shi wajen samar da robobi.Yana da kyakkyawar kwanciyar hankali na sinadarai, juriya na lalata da juriya na ruwa.
