Description

Carbonic Acid, Diphenyl Ester, Polymer With 1,6-Hexanediol is a high-performance polycarbonate diol, a key polymeric intermediate used in the synthesis of advanced polyurethanes and specialty polymers. Its value lies in providing a unique balance of flexibility, hydrolytic stability, and mechanical strength to the final polymer matrix. This material is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-grade thermoplastic polyurethanes (TPU).

Application

• High-Performance Polyurethane Elastomers (TPU/CPU): Serves as a critical soft segment component, imparting excellent low-temperature flexibility, abrasion resistance, and hydrolysis stability for applications like industrial hoses, seals, and cable sheathing.
• Coatings and Surface Finishes: Used in the synthesis of polyurethane dispersions (PUDs) and solvent-borne coatings for textiles, synthetic leather, and automotive interiors, providing durable, flexible, and chemical-resistant finishes.
• Adhesives and Sealants: A key building block for formulating moisture-curing and hot-melt adhesives with enhanced bond strength, elasticity, and long-term durability under varying environmental conditions.
• Specialty Resins and Modifiers: Employed as a polymeric diol to modify the properties of other resin systems, improving toughness, weatherability, and processing characteristics.
• Biomedical and Controlled Release Materials: Potential use in creating biocompatible and biodegradable polymer matrices for specialized medical devices and drug delivery systems, owing to its tunable degradation profile.

Quality Control

Our Carbonic Acid, Diphenyl Ester, Polymer With 1,6-Hexanediol is manufactured under strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value, acid value, molecular weight distribution, and moisture content to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to support your quality assurance and R&D processes.

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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential degradation.
