Description

Poly(Ethylene Adipate) is a high-performance, biodegradable polyester diol synthesized from ethylene glycol and adipic acid. This versatile polymer intermediate is valued for its excellent flexibility, low-temperature properties, and compatibility with other polymers, making it a critical component in advanced material formulations. It is primarily utilized in the production of high-quality polyurethanes, adhesives, coatings, and biodegradable plastics across the chemical manufacturing, automotive, and packaging industries.

Application

• Polyurethane Elastomers & Foams: A key soft segment component for producing flexible, resilient, and durable polyurethane (PU) materials used in automotive parts, footwear, and cushioning.
• Biodegradable & Aliphatic Polyesters: Serves as a precursor or modifier in the synthesis of environmentally friendly, compostable plastics and films.
• Adhesives & Sealants: Imparts flexibility and toughness to hot-melt and reactive adhesive systems, enhancing bond performance.
• Coating Resins: Used in the formulation of high-performance, flexible, and chemical-resistant coatings for industrial and protective applications.
• Plasticizers & Modifiers: Acts as an internal plasticizer or compatibilizer to improve the low-temperature flexibility and impact resistance of various polymer blends.
• Thermoplastic Polyurethanes (TPU): A fundamental building block for manufacturing TPUs used in wires, cables, hoses, and medical devices.

Quality Control

Our Poly(Ethylene Adipate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent properties such as hydroxyl value, acid value, molecular weight distribution, and moisture content. Certificates of Analysis (COA) are provided with every shipment, detailing the specifications for the specific grade supplied. We adhere to relevant industry standards and can support compliance requirements for your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents, acids, and bases.
