Description

Diethyl Ester Carbonic Acid Polymer With 1,6-Hexanediol is a specialized polycarbonate diol (PCD) prepolymer, synthesized from diethyl carbonate and 1,6-hexanediol. This high-performance intermediate is valued for its excellent hydrolytic stability, low-temperature flexibility, and resistance to oils and chemicals. It is primarily sought by manufacturers in the polyurethane, coatings, and specialty elastomers industries for creating durable, high-quality end products.

Application

• High-Performance Polyurethane Elastomers: Used as a soft segment to impart superior mechanical properties, abrasion resistance, and hydrolysis stability.
• Synthetic Leather and Artificial Leather Coatings: Provides excellent flexibility, durability, and a soft, natural feel in finish formulations.
• Adhesives and Sealants: Enhances the bonding strength, elasticity, and long-term durability of moisture-curing and hot-melt systems.
• Coating Resins: Serves as a key polyol component in high-end polyurethane coatings for automotive, industrial, and textile applications, offering outstanding weatherability.
• Thermoplastic Polyurethanes (TPU): A critical building block for producing TPUs with consistent quality, excellent processing characteristics, and enhanced product performance.
• Medical-Grade Polymers: Suitable for formulating biocompatible polyurethanes used in certain medical devices and applications due to its purity and stability.

Quality Control

Our production of Diethyl Ester Carbonic Acid Polymer With 1,6-Hexanediol adheres to stringent quality management systems to ensure batch-to-batch consistency and reliability. Key parameters such as hydroxyl value, molecular weight distribution, acid value, and color are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

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 container tightly sealed when not in use to prevent moisture absorption and potential quality degradation.
