Bahan lapisan sekunder kanggo kabel optik (PBT)
Katrangan singkat:
Bahan PBT kanggo tabung longgar serat optik minangka bahan PBT kinerja dhuwur sing dipikolehi saka partikel PBT umum sawise ekspansi rantai lan tackification.Nduwe sifat-sifat resistensi tensile, resistensi lentur, resistensi impact, penyusutan sing kurang, resistensi hidrolisis, lan liya-liyane, lan nduweni kinerja pangolahan sing apik lan kompatibilitas sing apik karo masterbatch warna PBT umum.Iki ditrapake kanggo kabel mikro, kabel sabuk lan kabel komunikasi liyane.
Standar: ROSH
Model: JD-3019
Aplikasi: Ditrapake kanggo ngasilake tabung serat optik
