Description

Neopentyl Glycol Propoxylate is a specialized polyether polyol derived from the propoxylation of neopentyl glycol. This compound is valued for its excellent hydrolytic stability, low viscosity, and ability to impart flexibility and weatherability to final polymer products. It is a critical intermediate for manufacturers in the polyurethane, coatings, and resin industries seeking to enhance product performance and durability. Its unique branched structure contributes to superior chemical resistance and lower crystallinity in formulated systems.

Application

• As a key monomer and chain extender in the production of high-performance polyurethane resins for coatings, adhesives, sealants, and elastomers (CASE).
• Used in formulating saturated polyester resins for industrial and automotive coatings, providing excellent gloss retention and weather resistance.
• Serves as a building block for plasticizers and lubricant additives, improving low-temperature properties and stability.
• Employed in the synthesis of radiation-curable oligomers for UV-curable inks, coatings, and 3D printing resins.
• Acts as an intermediate for surfactants and emulsifiers used in specialty chemical formulations.
• Utilized in the production of alkyd resins for decorative and protective paints.

Quality Control

Our Neopentyl Glycol Propoxylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in hydroxyl value, viscosity, water content, and acid value, meeting precise customer specifications. A comprehensive Certificate of Analysis (COA) documenting all key parameters is provided with every shipment. We adhere to relevant industry standards and can support compliance needs for global markets.

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/59-77°F). This material is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and potential oxidation. Keep away from heat, sparks, and open flames.
