Soundproof PP pipes and fittings

The sound absorbing interior sewage system PP ULTRA dB is a complete pipe and fittings system in polypropylene enriched with mineral compounds.

The pipes are manufactured through the co-extrusion method with structured walls: the interior layer coloured in white, allows easy inspection and the exterior layer coloured in blue is resistant to dirt and is foreseen with permanent marking at every centimetre. The fittings are done by injection.

The excellent properties of raw materials: high impact resistance, resistance to chemical substances and high temperatures, high sealing, reduced weight and easy installation are the reason why the products in polypropylene enhanced with mineral compounds have become more and more popular.
