Authentic large calcite, just what I want, the PVC pipe produced is very beautiful, it is milky white with good toughness, it is not as blue as the previous pipe, thank you Yeda for your service

Took a ton of samples, the sample results are quite good, high temperature resistance does not change color, liquidity and whiteness are good, much better than the northern calcium powder used before, the boss is also very professional, warm attitude, I hope the vehicle delivery quality stability.

Tony is a good partner. In addition to the product itself, he also gave me a lot of useful suggestions during the cooperation.

The product is really good, but the freight is a little bit expensive. I hope the economy will get better soon and the transportation cost will return to normal. The service is good, and it is an excellent enterprise

A reliable supplier, the boss is also very nice smooth together, the quality of powder is very good, will maintain long-term cooperation

Cooperation for many years, has not had a problem, very good!
