Calcium carbonate serves as a cost-effective filler that allows manufacturers to use less PVC resin in the production of pipes. The mineral’s unique properties enable it to blend seamlessly with the PVC compound, ensuring that the pipes maintain their structural integrity and durability. This reduction in resin usage directly translates to less reliance on petrochemical resources, aligning with the broader goals of resource conservation and sustainable manufacturing. https://www.zjhongtian.com/news/industry-news/the-use-of-calcium-carbonate-in-pvc-pipes.html
