Description

Poly(Ethylene Glycol) Dibenzoate is a high-purity benzoate ester derivative of polyethylene glycol, valued for its excellent solvency and plasticizing properties. This versatile chemical intermediate is crucial for formulators seeking to enhance flexibility, compatibility, and processing characteristics in polymer systems. It is primarily utilized by manufacturers in the plastics, adhesives, coatings, and personal care industries for its reliable performance and broad material compatibility.

Application

• Plasticizer for Polymers: Acts as a secondary plasticizer and compatibilizer in PVC, polyurethane, and other resin formulations to improve flexibility and processability.
• Adhesive & Sealant Formulations: Serves as a tackifier and rheology modifier, enhancing bond strength and application properties in solvent-based and hot-melt adhesives.
• Coating Additive: Used as a film-forming agent and coalescing aid in industrial and decorative coatings to improve gloss, flow, and substrate wetting.
• Personal Care & Cosmetics: Functions as an emollient and solvent in creams, lotions, and makeup, providing smooth texture and even pigment dispersion.
• Lubricant and Mold Release Agent: Employed in plastic and rubber processing as an internal lubricant and external mold release agent to reduce friction and prevent sticking.
• Chemical Intermediate: Used in the synthesis of more complex esters, surfactants, and specialty chemicals requiring a PEG-benzoate backbone.
