Airedale Chemical Phosphorous Acid is the compound described by the formula H3PO3. This acid is diprotic in that it readily ionizes two protons not triprotic.
Airedale Chemical Phosphorous Acid is an intermediate in the preparation of other Phosphorus compounds. In solid form Airedale Chemical Phosphorous Acid is a white crystal with a distinctive odour. In solution form Airedale Chemical Phosphorous Acid is a clear to colourless liquid with a distinctive odour.
Phosphorus based flame retardants are easy to process halogen free compounds which offer excellent fire safety performance. They are widely used in plastics, polyurethane foams, coatings, and textiles. Phosphate esters are found in PVC, polycarbonate/ acrylonitrile butadiene styrene (PC/ABS) blends and polycarbonate, and act as good plasticizers e.g. tricresyl phosphate, triphenyl phosphate and dimethylpropane phosphonate. Phosphonates and phosphinates are used in flexible polyurethane foams for automotive and building applications.
