Description

1,3-Dioxolan-2-One Polymer With 1,4-Butanediol And 1,6-Hexanediol is a specialized polycarbonate diol, a high-performance polymer intermediate synthesized from cyclic carbonate and diols. This compound is valued for its ability to impart excellent mechanical properties, hydrolysis resistance, and flexibility to polyurethane and other polymer systems. It is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and performance.

Application

• High-Performance Polyurethane Elastomers: Used as a soft segment to create elastomers with superior tensile strength, abrasion resistance, and low-temperature flexibility.
• Waterborne & Solvent-Based Coatings: Serves as a key polyol component for producing coatings with excellent weatherability, chemical resistance, and adhesion to various substrates.
• Adhesives and Sealants: Imparts enhanced cohesion, elasticity, and durability to structural and pressure-sensitive adhesives, as well as high-performance sealants.
• Thermoplastic Polyurethanes (TPU): A critical building block for manufacturing TPUs used in films, fibers, and molded parts requiring a balance of hardness and elasticity.
• Biomedical Polymers: Potential applications in the synthesis of biocompatible and biodegradable polymers for specialized medical devices and controlled-release systems.
• Specialty Resins and Composites: Acts as a modifier to improve the toughness and impact resistance of epoxy and other thermoset resin systems.

Quality Control

Our 1,3-Dioxolan-2-One Polymer With 1,4-Butanediol And 1,6-Hexanediol is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent hydroxyl value, viscosity, molecular weight distribution, and moisture content, meeting precise customer specifications. Comprehensive Certificates of Analysis (COA) detailing all critical parameters are provided to guarantee traceability and compliance with your formulation requirements.

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