A penny for a shipment. The main problem is the proportion of calcium powder. The price of calcium powder is relatively high. Therefore, if the content of calcium powder in the PVC hose is high, the corresponding price is relatively high, and vice versa.

One of the reasons why the quality of pvc hoses is continuously improving is to carry out the principle of “price based on prices” and appropriately open quality spreads. In accordance with the quality of pvc hoses, graded pricing will be used to achieve high quality and low prices, and low quality reserve prices. Same price. In the course of our daily purchasing of PVC pipes, we distinguish prices based on the quality of pvc hoses and the quality of materials used in pvc hoses.
