Description

Poly(1,2-Butylene Glycol) is a versatile polymeric glycol derived from 1,2-butanediol. This compound serves as a valuable intermediate and functional additive, prized for its ability to modify properties such as flexibility, hydrophilicity, and viscosity in various formulations. It is essential for manufacturers in the polymer, personal care, and specialty chemical industries seeking reliable performance materials.

Application

• As a polymeric plasticizer and softener in polyurethane (PU) elastomers and coatings.
• As a hydrophilic modifier and viscosity control agent in personal care products and cosmetics.
• As a reactive intermediate in the synthesis of specialty polyesters and alkyd resins.
• As a humectant and carrier fluid in industrial lubricants and functional fluids.
• As a building block for water-soluble or biodegradable polymers.
• In the formulation of adhesives, sealants, and inks to adjust rheological properties.

Quality Control

Our Poly(1,2-Butylene Glycol) is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in molecular weight distribution, hydroxyl value, viscosity, and moisture content. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture.
