Description

1,4-Benzenedicarboxylic acid polymer with 1,4-butanedicarboxylic acid, 1,2-ethanediol, 2-ethyl-2-hydroxymethyl-1,3-propanediol, 1,1-[(1-methylethylidene )bis(4,1-phenyleneoxy)] bis[2-propanol] is a high-performance, branched polyester polyol designed for advanced material synthesis. This specialized polymer is engineered to impart enhanced mechanical properties, chemical resistance, and thermal stability to final products. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing high-grade polyurethane foams and resins.

Application

• High-Performance Polyurethane Coatings: Serves as a key polyol component for producing durable, weather-resistant, and chemical-resistant industrial and protective coatings.
• Advanced Adhesives & Sealants: Used in formulating structural adhesives and high-performance sealants requiring excellent flexibility and adhesion.
• Elastomer Production: A building block for manufacturing polyurethane elastomers with superior tensile strength, abrasion resistance, and elasticity.
• Rigid & Flexible Foam Systems: Imparts improved dimensional stability and load-bearing properties to polyurethane foams used in insulation and cushioning.
• Composite Materials: Acts as a reactive modifier or crosslinker in resin systems for fiber-reinforced composites.
• Specialty Polymer Synthesis: Utilized in R&D for creating novel copolymers with tailored properties for niche industrial applications.

Quality Control

Our production of this specialty polyester polyol adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acid value, viscosity, and moisture content are rigorously tested. A comprehensive Certificate of Analysis (COA) detailing all specifications 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, 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, which can affect product performance. Keep away from strong oxidizers and heat sources.
