Materyèl kouch segondè pou kab optik (PBT)
Deskripsyon kout:
Materyèl PBT pou fib optik tib ki lach se yon kalite materyèl PBT pèfòmans segondè jwenn nan patikil PBT komen apre ekspansyon chèn ak tackification. Li gen pwopriyete ekselan nan rezistans rupture, rezistans koube, rezistans enpak, kontraksyon ki ba, rezistans idroliz, elatriye, e li gen ekselan pèfòmans pwosesis ak bon konpatibilite ak komen PBT koulè masterbatch. Li aplike nan mikwo kab, kab senti ak lòt câbles kominikasyon.
Estanda: ROSH
