One of the key functions of calcium carbonate for PVC pipes is to improve the dimensional stability of the pipes. By adding calcium carbonate, manufacturers can produce pipes that resist deformation, even under significant stress. This enhances the durability of PVC pipes, allowing them to withstand harsh environmental conditions, such as fluctuating temperatures and mechanical pressure, without cracking or warping. Flexibility is a critical factor for many applications of PVC pipes. Pipes used in irrigation, plumbing, and industrial systems often require a certain degree of flexibility to accommodate the movement and pressure they are subjected to. Calcium carbonate for PVC pipes plays a key role in maintaining this flexibility while still providing structural support. https://www.zjhongtian.com/news/industry-news/the-use-of-calcium-carbonate-in-pvc-pipes.html
