The difference between them is whether or not they are coated with a plasticizer: PVC is coated with a plasticizer, while uPVC is not. Plasticizers make PVC malleable and flexible, making it ideal for wires, toys, shower curtains and even clothing. uPVC, on the other hand, is hard and lacks flexibility, making it more suitable for window frames and plumbing. uPVC, on the other hand, is hard and inflexible, making it more suitable for window frames and plumbing. In addition, PVC contains toxins (Bisphenol A and phthalates to be precise) whereas uPVC is toxin-free. uPVC is a maintenance-free material whereas PVC is a less durable, porous and flexible material. However, both PVC and uPVC have limited color options.
Plasticizers added
CPVC pipe has added plasticizers, while UPVC pipe does not contain any plasticizers.
Bendability
Since UPVC pipes do not contain plasticizers, they are very hard and cannot be bent. In contrast, CPVC pipe is quite soft and can be bent.
Temperature Resistance
CPVC pipes can withstand both high and low temperatures, whereas UPVC pipes can only supply water at low temperatures.
