Description

Propyleneglycol,Polymer With Maleic Anhydride,2,2-Dimethyl-1,3-Propanediol And 4,4'-Isopropyliden Biscyclohecylalcohol CAS NO 51937-07-6 is a specialized, high-performance polyester polyol copolymer designed for demanding industrial applications. This compound is engineered to deliver exceptional thermal stability, hydrolytic resistance, and tailored reactivity, making it a critical intermediate for advanced material synthesis. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-end polyurethane resins and specialty polymers.

Application

• High-Performance Polyurethane Systems: As a key polyol component for manufacturing rigid and flexible foams, elastomers, and coatings with enhanced durability and chemical resistance.
• Industrial and Protective Coatings: Used in formulating powder coatings, coil coatings, and corrosion-resistant industrial finishes that require excellent weatherability and adhesion.
• Specialty Adhesives and Sealants: Imparts flexibility, strength, and environmental stability to structural adhesives, potting compounds, and high-performance sealants.
• Elastomer Production: Serves as a building block for castable polyurethane elastomers used in rollers, wheels, and industrial parts requiring abrasion resistance.
• Resin Modification: Acts as a modifier for alkyd, polyester, and other resins to improve flexibility, impact resistance, and compatibility with other components.
• Composite Materials: Utilized in the production of fiber-reinforced plastics (FRP) and other composite materials for automotive and aerospace applications.

Quality Control

Our production of this specialty polyester polyol adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture, which can affect product performance.
