SILKE LYSIi-silicone masterbatchkufakwe ungqimba lwangaphakathi lwe-HDPEIpayipi le-Telecom, kunciphisa i-coefficient of friction ngaleyo ndlela kwenza kube lula ukushaywa kwezintambo ze-optic fiber kude. Ingqimba yayo yangaphakathi ye-silicon core ikhishwa ngaphakathi kodonga lwepayipi ngokuvumelanisa, isatshalaliswa ngokulinganayo odongeni lonke lwangaphakathi, ingqimba ye-silicon core inokusebenza okufanayo ngokomzimba nangokomshini njenge-HDPE: akukho ukuxebuka, akukho ukuhlukaniswa, kodwa ngokugcotshwa okuhlala njalo.

Ifanele izinhlelo zamapayipi ze-PLB HDPE telecom duct, ama-duct e-silicon core, i-fiber optical yokuxhumana kwangaphandle, ikhebula le-fiber optical, kanye nepayipi elikhulu lobubanzi, njll.
