Smooth surface: Small friction coefficient to ensure the cables go through smoothly Fire resistance: Self-extinguishing, do not support combustion Corrosion Resistance: Resistant to acids, bases and salts, assuring a lower maintenance cost and a longer performance life

Fire resistance: Self-extinguishing, do not support combustion Impact strength: Resistant to compression and impact, suitable to be buried in concrete Easy Installation: solvent cement and threading joining

Non-conductive: Good insulation, assuring a safe system Smooth surface: Small friction coefficient to ensure the cables go through smoothly Fire resistance: Self-extinguishing, do not support combustion
