Description

Poly(Tetrahydrofuran-Co-Neopentanediol) is a high-performance, segmented polyether polyol copolymer. This engineered material offers a unique balance of flexibility, hydrolytic stability, and low-temperature properties, making it a critical component in advanced polymer formulations. It is essential for manufacturers in the polyurethane, coatings, and specialty elastomer industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Elastomers: Used as a soft segment to impart excellent flexibility, resilience, and low-temperature impact resistance in cast elastomers, thermoplastic polyurethanes (TPU), and millable gums.
• Coatings and Adhesives: Serves as a key polyol in formulations for moisture-curable, abrasion-resistant coatings, sealants, and adhesives requiring superior weatherability and chemical resistance.
• Specialty Copolymers and Modifiers: Acts as a polymeric modifier or compatibilizer to improve the low-temperature flexibility and toughness of engineering plastics and other rigid polymers.
• Fiber and Textile Finishing: Employed in the synthesis of polyurethane dispersions (PUDs) for durable, flexible coatings on synthetic leather, fabrics, and technical textiles.
• Resilient Foams: Utilized in the production of microcellular foams and other specialized foam products where a combination of softness and structural integrity is required.

Quality Control

Our Poly(Tetrahydrofuran-Co-Neopentanediol) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in hydroxyl value, molecular weight distribution, 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, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and oxidation. Keep away from strong oxidizers and heat sources.
