I-SILKE LYSI silicone masterbatch esetshenziswa kungqimba lwangaphakathi lwepayipi eliyinhloko le-HDPE silicon, inciphisa i-coefficient of friction futhi ngaleyo ndlela yenza kube lula ukushaywa kwezintambo ze-optic fiber kude. Ingqimba yayo eyinhloko ye-silicon yodonga lwangaphakathi ikhishwa ngaphakathi kodonga lwepayipi ngokuvumelanisa, isatshalaliswa ngokulinganayo odongeni lwangaphakathi lonke, ungqimba oluyinhloko lwe-silicon lunokusebenza okufanayo ngokomzimba nangokomshini njenge-HDPE: akukho ukuxebuka, akukho ukuhlukaniswa.

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.
