Secondary coating material yeOptical cable (PBT)
Tsanangudzo Pfupi
PBT zvinhu zve optical fiber loose chubhu imhando yekushanda kwepamusoro PBT zvinhu zvakawanikwa kubva kune zvakajairika PBT zvimedu mushure mekuwedzera cheni uye tackification. Iyo ine yakanakisa zvimiro zvekutsiga kuramba, kukotama kuramba, kukanganisa kukanganisa, kuderera kuderera, hydrolysis kuramba, nezvimwewo, uye ine yakanakisa kugadzirisa mashandiro uye kuenderana kwakanaka neyakajairwa PBT ruvara masterbatch. Inoshandiswa kune micro tambo, bhandi tambo uye mamwe tambo dzekukurukurirana.
Standard: ROSH
Muenzaniso: JD-3019
Kushanda: Inoshandiswa kugadzira optical fiber loose chubhu
