Description

Polyester CAS NO 113669-97-9 is a high-performance synthetic polymer characterized by its versatile chain structure and excellent material properties. This compound is engineered to deliver superior durability, chemical resistance, and thermal stability, making it a critical raw material for advanced manufacturing. It is essential for industries requiring robust and reliable polymeric materials for coatings, adhesives, and engineered plastics.

Application

• Industrial Coatings and Paints: Used as a primary resin in high-performance coatings for automotive, appliance, and coil applications, providing excellent gloss, hardness, and weatherability.
• Adhesives and Sealants: Serves as a key component in formulating structural and hot-melt adhesives, offering strong bonding strength and flexibility.
• Engineering Plastics and Composites: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and composite materials for automotive parts, electrical components, and consumer goods.
• Textile Finishing and Nonwovens: Employed in fabric coatings and binders for technical textiles to impart water resistance, durability, and specific functional properties.
• Packaging Materials: Utilized in the production of films, laminates, and rigid packaging that require excellent barrier properties and mechanical strength.
• Industrial Fiber Production: A precursor for high-tenacity fibers used in tire cord, conveyor belts, and other industrial fabric applications.

Quality Control

Our Polyester products are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a series of analytical tests including viscosity, acid value, hydroxyl value, and gel time measurements. Certificates of Analysis (COA) documenting all critical parameters are available upon request 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 a temperature between 15-25°C (59-77°F). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent oxidation and moisture absorption.
