Application
Key Applications:
1. Plasticizers: A primary raw material for producing phthalate plasticizers, which are used to increase the flexibility and durability of plastics, particularly PVC. 2. Polyester Resins: Used in the manufacture of unsaturated polyester resins, which are essential in fiberglass-reinforced plastics for automotive parts, marine applications, and construction materials. 3. Alkyd Resins: Employed in the production of alkyd resins, which are used in paints, coatings, and varnishes to enhance durability and gloss. 4. Dyes and Pigments: Acts as an intermediate in the synthesis of various dyes and pigments.
