Polyphosphoric Acid

This is a mixture composed of orthophosphoric acid and compounds formed by the dehydration condensation of orthophosphoric acid. Our company manufactures and sells 105% and 116% polyphosphoric acid which are relatively easy to handle. However, both of these products are in a supercooled liquid state and can readily solidify.
