Esters (Plasticizers)
Phthalic anhydride is produced by the oxidation of naphthalene and o-xylene; it is a key raw material for the manufacture of plasticizers as well as alkyd resins (used in coatings, varnishes, and paints) and unsaturated polyester resins (UPR), and is also utilized in the pharmaceutical industry and in the production of flame retardants.
Phthalic acid esters are primarily used as plasticizers. They are added to rigid polymers (especially polyvinyl chloride—PVC) to impart flexibility, ductility, and durability.
Phthalic anhydride (flakes / molten) Chemical name: Phthalic anhydride | Diisononyl phthalate (DINP) Chemical name: Diisononyl phthalate |
Dipropylheptylphthalate (DPHP) Chemical name: Bis (2-propylheptyl) phthalate | |
| We have long maintained and continue to strengthen our position in the production of high-molecular-weight plasticizers, particularly diisononyl phthalate and dipropylheptyl phthalate. | |
