Key Differences
UPVC, or unplasticized polyvinyl chloride, is a rigid form of PVC known for its robustness and lack of flexibility, whereas CPVC, standing for chlorinated polyvinyl chloride, undergoes a chlorination process that enhances its temperature resistance.
UPVC is commonly used in building applications like window frames and doors due to its durability and low maintenance, while CPVC, thanks to its higher temperature tolerance, is mainly employed in hot and cold water distribution systems.
UPVC benefits include resistance to corrosion, weathering, and chemical rotting, while CPVC has the additional advantage of being able to withstand higher temperatures, making it more suitable for transporting hot liquids.
UPVC often comes in a white or cream color, offering a clean aesthetic for residential applications, whereas CPVC usually appears in a light yellow or tan shade, signaling its difference and specialized purpose.
Both UPVC and CPVC offer cost-effective solutions in their respective fields, but the choice between them largely depends on the specific application: UPVC for structural uses and CPVC for plumbing.
