Phthalic anhydride (PA) is a white crystalline compound used to manufacture plasticizers, pigments, dyes and resins. One major consumer of PA is the phthalate plasticiser industry, the products of which are used to produce flexible plastic products such as wire & cable applications, hoses, pipes, coated fabrics, roofing membranes and swimming pool liners.
