Description

Poly[Di(Ethylene Glycol)/Trimethylolpropane-Alt-Adipic Acid] is a specialized polyol ester, a key building block in the synthesis of high-performance polymers. This compound is valued for its ability to impart flexibility, hydrolytic stability, and tailored reactivity into final polymer networks. It is primarily required by manufacturers in the polyurethane, resin, and specialty coatings industries for producing elastomers, adhesives, and flexible coatings.

Application

• Polyurethane Elastomers & Foams: Serves as a reactive polyol component to create flexible foams, sealants, and elastomers with enhanced durability.
• Saturated Polyester Resins: Used in the formulation of alkyd and polyester resins for coatings, providing improved flexibility and adhesion.
• Adhesives & Sealants: Acts as a polymeric plasticizer and backbone modifier to adjust the flexibility and tack of adhesive formulations.
• UV-Curable Resins & Inks: Functions as a reactive diluent or oligomer in radiation-curable systems for coatings and graphic arts.
• Plasticizers & Lubricant Additives: Employed as an intermediate for synthesizing polymeric plasticizers and specialty lubricant components.
• Cross-linking Agent: Utilized in thermoset systems where its multiple hydroxyl groups contribute to network formation and cross-link density.

Quality Control

Our production of Poly[Di(Ethylene Glycol)/Trimethylolpropane-Alt-Adipic Acid] adheres to stringent quality management protocols. Each batch undergoes rigorous testing for key parameters including hydroxyl value, acid value, viscosity, and water content to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) documenting full specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture uptake and oxidation.
