The term “canceled UPVC USE” likely refers to the cancellation or discontinuation of a specific use case for unplasticized polyvinyl chloride (UPVC) products. UPVC, commonly used in pipes and window frames, can be employed in various applications, including plumbing, drainage, electrical conduits, and construction. Cancellation of a UPVC use case could stem from various reasons, such as product development, changing market demands, or the introduction of alternative materials.
