Optik kabel uchun ikkilamchi qoplama materiali (PBT)
Qisqacha tavsif:
Optik tolali bo'sh trubka uchun PBT materiali zanjirning kengayishi va yopishqoqligidan keyin umumiy PBT zarralaridan olingan yuqori samarali PBT materialidir. U valentlik qarshiligi, egilish qarshiligi, zarba qarshiligi, past siqilish, gidrolizga chidamlilik va boshqalarning ajoyib xususiyatlariga ega va mukammal qayta ishlash ko'rsatkichlariga ega va umumiy PBT rangli masterbatch bilan yaxshi mos keladi. Mikro kabel, kamar kabeli va boshqa aloqa kabellari uchun qo'llaniladi.
Standart: ROSH
Model: JD-3019
Ilova: Optik tolali bo'sh trubka ishlab chiqarish uchun qo'llaniladi
