Description

1,2-Ethanediol, Polymer With 1,12- Dodecanedioic Acid is a high-performance, linear aliphatic polyester derived from ethylene glycol and dodecanedioic acid. This polymer is valued for its excellent thermal stability, flexibility, and compatibility, making it a versatile building block for advanced material formulations. It is primarily sought by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Polymer Modifier: Used as a chain extender or soft segment in polyurethane and polyester elastomers to improve flexibility and low-temperature performance.
• Hot-Melt Adhesives: Serves as a key component to provide tack, adhesion, and thermal stability in packaging and construction adhesives.
• Powder Coatings: Acts as a resin modifier in thermosetting powder coatings to enhance flow, leveling, and final film properties.
• Engineering Plastics: Incorporated as a comonomer to tailor the crystallinity and mechanical properties of specialty nylons and copolyesters.
• Synthetic Lubricants & Plasticizers: Utilized in the formulation of high-performance synthetic esters for lubricants and as polymeric plasticizers for PVC.
• Fiber & Film Production: Employed in the manufacture of specialty fibers and biodegradable films requiring specific melt and tensile characteristics.

Quality Control

Our production of 1,2-Ethanediol, Polymer With 1,12- Dodecanedioic Acid adheres to stringent quality management protocols. Each batch is characterized for critical parameters including acid value, hydroxyl value, molecular weight distribution, and thermal properties to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
