117% Polyphosphoric Acid PPA CAS Number 8017-16-1
Polyphosphoric Acids
Chemical formula: H6P4O13
Molecular weight: 337.93
CAS: 8017-16-1
PPA is colorless transparent viscous liquid, hygroscopic, non-crystallizable,corrosive, water soluble into orthophosphate acid. Acidity is weaker than nitric acid and sulfuric acid. Non-oxidicability, could cause burns when meeting H vesicant. Specific gravity is 2.1g/cm3. Normal boiling point is 856ºC, keeping hard glassy block upon lowtemperature and liquid when heating up to 50~60ºC. Relative density is 1.987(P2O5 80.0%); 2.052(P2O5 84.0%); 2.084(P2O5 86.0%). Hazard label 20 (corrosives acidic properties). High viscidity, hard to stir or pour under normal temperature, and easily to operate when temperature is above 60ºC, omit heat when soluble in water, should be under ice-bath station when making dilution.

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.
- Some hot sale products are in stock, ready to ship.
- Professional manufacturer with high-quality phosphate products.
- Adherance to customers requirements and delivery instructions.
- Cost savings & supply security.
- Strict control and quality inspection.
