Description

1,3-Benzenedicarboxylic Acid, Polymer With 1,2-Ethanediol, Nonanedioic Acid And 2,2'-Oxybis [Ethanol] is a high-performance, branched polyester polyol designed for demanding industrial applications. This specialized polymer offers a unique balance of flexibility, chemical resistance, and thermal stability derived from its multi-acid and glycol composition. It serves as a critical raw material for formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for polyurethane foam production. Its consistent quality and reliable performance are essential for manufacturers seeking to enhance the durability and properties of their final products.

Application

• Polyurethane Elastomers: As a key polyol component for producing flexible, abrasion-resistant, and durable elastomers used in industrial wheels, rollers, and gaskets.
• Coatings and Paints: Used in high-performance polyurethane coatings to impart excellent adhesion, chemical resistance, and weatherability for industrial, automotive, and marine applications.
• Adhesives and Sealants: Serves as a backbone resin in formulating structural adhesives and flexible sealants with strong bonding properties and environmental resistance.
• Flexible Foams: Can be utilized in the production of specialized flexible polyurethane foams requiring specific resilience and load-bearing characteristics.
• Thermoplastic Polyurethanes (TPU): Acts as a polyol intermediate in the synthesis of TPUs for films, sheets, and molded parts.
• Resin Modifiers: Employed to modify the properties of other polymer systems, enhancing flexibility, toughness, and compatibility.

Quality Control

Our production of this polyester polyol adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and molecular weight distribution are rigorously monitored using advanced analytical techniques including titration, gel permeation chromatography (GPC), and FTIR. A comprehensive Certificate of Analysis (COA) detailing all specification results is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from strong oxidizers, acids, and bases.
