A relatively simple way is to determine whether calcium carbonate is added by testing the density of PPR water pipes. The density of normal PPR water pipes should be 0.89-0.91g/cm3. The density of calcium carbonate is above 2.7g/cm3, so if calcium carbonate is added, the overall density of the PPR water pipe will be higher than the normal 0.89-0.91g/cm3 density range.

Ningbo Sunplast Pipe Co., Ltd has been focusing on manufacturing of plastic piping systems for more than 15 years. We started the business as a micro factory which had less 5 workers & only one extrusion line for 20-315mm HDPE pipe, but now, we have been growing to be a modern international factory owning three manufacturing workshops & more than 200 workers.
