Company Information
ChuanLin Chemicals were founded in 2000. In the year or 2005 we started to develop an annual 20,000MT poly phosphate production line which successfully to be put into production in 2008.
In 2013,we purchased Mianyang chemical company as a new production area.We set up some new projects with advance technology in this area,including:
Annual 6,000 tons of phosphorus pentoxide production line;
Annual 2,000 tons of pyrophosphorus cupric production line;
Annual 4,000 tons of polyphosphoric acid production line;
Annual 5,000 tons of red phosphorus(and also coated red phosphorus) production line;
Annual 2,000 tons of water soluble ammonium polyphosphate production line;
And new production lines for our other products.
In 2009,we set up new office in Guanzhou.And we will also found new office in Korea and European.
In 2021,we established new factory for research and develop new phosphorus material,as well as production.
