Description

1,6-Hexanediol, Distn. Overheads is a specific distillation fraction obtained during the purification of 1,6-Hexanediol, primarily consisting of related diols, polyols, and reaction intermediates. This product stream offers significant value as a cost-effective raw material for applications where the exact composition of pure 1,6-Hexanediol is not critical. It is particularly sought after by manufacturers in the polymer and chemical synthesis industries for producing polyurethanes, plasticizers, and as a building block for various specialty chemicals.

Application

• As a reactive intermediate in the synthesis of polyester polyols for flexible and rigid polyurethane foams.
• As a component in the production of plasticizers and lubricants.
• As a starting material or chain extender in the manufacture of coatings, adhesives, sealants, and elastomers (CASE).
• In the synthesis of UV-curable resins and other radiation-curable materials.
• As a precursor for specialty surfactants and corrosion inhibitors.
• For research and development purposes in organic synthesis and polymer chemistry.

Quality Control

Our 1,6-Hexanediol, Distn. Overheads is produced under a stringent quality management system. Each batch is analyzed to ensure consistent composition and performance for its intended industrial applications. Key parameters such as hydroxyl value, water content, and color are monitored. A Certificate of Analysis (COA) detailing the specific batch characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is 15-25°C.
