Description

Glycerid, C16-18 Und C18-Unges., Polymer Mit Glycerin Und Phthalsureanhydrid is a polymeric ester synthesized from glycerin, phthalic anhydride, and a blend of C16-C18 saturated and unsaturated fatty acids. This versatile chemical intermediate is valued for its ability to impart flexibility, adhesion, and hydrophobic properties in formulated products. It is primarily utilized by manufacturers in the coatings, polymer modification, and specialty chemical industries seeking to enhance material performance.

Application

• As a plasticizer and modifier in polyvinyl chloride (PVC) and other polymer systems to improve flexibility and processability.
• As a key building block in the synthesis of alkyd resins for industrial and decorative coatings, providing durability and gloss.
• As a rheology modifier and dispersing agent in pigment pastes, inks, and adhesive formulations.
• In the production of specialty lubricants and grease thickeners where thermal stability and water resistance are required.
• As a hydrophobic agent in construction materials and sealants to reduce water absorption.
• For use in epoxy curing agents and cross-linkers to tailor the mechanical properties of thermoset polymers.
