Product Description
Poly Phosphoric Acid (PPA) is a clear colorless to pale yellow liquid that is highly hygroscopic and exhibits high viscosity. With a molecular weight of 337.93 g/mol and a melting point of 54C, PPA is a strong dehydrating agent that has a refractive rate of 1.433. It is primarily used in chemical synthesis as a binder in asphalt modification and in manufacturing specialty chemicals. PPA is fully soluble in water and has a pH level of 1-2 (in aqueous solution). Its structural formula is (HPO3)n, and its molecular formula is H6P4O13. PPA is a pungent-smelling, poisonous industrial-grade substance that is typically 95-99% pure. To enhance its shelf life, it should be stored in a cool, dry, and well-ventilated area away from incompatible materials.
