Raw Material

Orthoxylene (OX) is the second largest of the three commercial isomers of xylene. Almost all OX output is consumed in the manufacture of phthalic anhydride (PA), which has three principal uses: phthalate plasticisers used in the compounding of polyvinyl chloride (PVC) resins; unsaturated polyesters resins (UPRs) used in glass-reinforced thermoset engineering applications; and alkyd resins used mainly for surface coatings.
