Description

Poly(2-Methyl-1 3-Propylene Adipate) is a specialized polyester polyol derived from adipic acid and 2-methyl-1,3-propanediol. This compound is valued for its role as a key intermediate in the synthesis of high-performance polyurethanes, offering tailored flexibility and resilience to the final polymer network. It is primarily sought by manufacturers in the polyurethane elastomer, adhesive, coating, and sealant industries for formulating products with specific mechanical and chemical resistance properties.

Application

• Polyurethane Elastomers: Serves as a soft segment component to impart flexibility, toughness, and hydrolytic stability to cast elastomers and thermoplastic polyurethanes (TPU).
• Adhesives & Sealants: Used in the formulation of moisture-curing and hot-melt polyurethane adhesives, providing excellent adhesion and durability.
• Coatings: A crucial building block for polyurethane coatings, contributing to weatherability, abrasion resistance, and flexibility in industrial and protective coatings.
• Flexible Foams: Can be utilized in the production of specialized flexible polyurethane foams requiring specific resilience profiles.
• Resin Modification: Acts as a polymeric plasticizer or modifier for other resin systems to enhance impact resistance and low-temperature performance.
• Synthetic Lubricants: Employed in the creation of ester-based synthetic lubricants and functional fluids.

Quality Control

Our production of Poly(2-Methyl-1 3-Propylene Adipate) adheres to stringent quality management protocols. Each batch is characterized for critical parameters including hydroxyl value, acid value, viscosity, and water content to ensure consistency and performance in downstream applications. 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. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
