Let's first understand the basics before talking about UPVC Pipes Manufacturers in India. Hard PVC is another name for plasticized PVC, which is referred to as UPVC. This indicates that the PVC compound has not been given any plasticizer. The most popular PVC kinds for the transportation of drinking water, waste materials, sewage, and subsurface drainage systems are UPVC pipes and fittings. They are manageable and lightweight. They are completely recyclable, have good mechanical performance, long-lasting durability, chemical and UV resistance, and high durability.
