PVC and uPVC differ mainly in strength and application. PVC (Polyvinyl Chloride) is flexible, lightweight, and commonly used for drainage, electrical conduits, and insulation due to its cost-effectiveness. uPVC (Unplasticized PVC) is rigid, durable, and resistant to chemicals, UV rays, and weather conditions, making it ideal for water supply pipes, doors, and windows. Compared to PVC, uPVC offers higher longevity, better pressure handling, and superior performance in plumbing and construction applications.
