PVC-U is unplasticised PVC, which means no plasticiser (US: plasticizer) has been added to the PVC compound. Unplasticised PVC is also known as rigid PVC. PVC-U is the most common PVC type for pipes and fittings including transportation of drinking water, soil and waste, sewage and underground drainage and industrial applications.
They are a safe choice for transportation of drinking water, light and easy to handle and affordable. Technical properties include high
mechanical performance, high durability (at least 100 years for underground pipes), high chemical resistance and resistance to UV
exposure. Moreover, PVC-U pipes have favorable environmental profiles and are 100% recyclable.
