Description

Propylene Glycol, Glycerin, Adipic Acid, Isophthalic Acid Polymer is a specialized polyester polyol, a key intermediate in the production of high-performance polyurethanes and coatings. This compound matters for its ability to impart specific mechanical properties, chemical resistance, and flexibility to final polymer products. It is primarily needed by manufacturers in the polyurethane foam, elastomer, adhesive, and specialty coating industries seeking tailored polymer backbones.

Application

• Flexible Polyurethane Foam: Serves as a key polyol component for producing soft, resilient foams used in furniture, bedding, and automotive seating.
• Polyurethane Elastomers: Used in the synthesis of elastomers for applications requiring durability, such as industrial wheels, seals, and gaskets.
• Coatings and Adhesives: Acts as a building block in polyester resins for high-performance protective coatings, paints, and structural adhesives.
• Rigid Foam Systems: Incorporated into formulations for rigid insulation foams used in construction and appliance insulation.
• Specialty Polymer Synthesis: Utilized as a macromonomer or cross-linker in the production of engineered plastics and composite materials.

Quality Control

Our Propylene Glycol, Glycerin, Adipic Acid, Isophthalic Acid Polymer undergoes rigorous quality testing to ensure batch-to-batch consistency and performance in downstream formulations. Quality is monitored against key parameters including hydroxyl value, acid value, viscosity, and water content. Certificates of Analysis (COA) detailing these specifications 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, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption which can affect product performance.
