Description

Polycaprolactone Triol Average Mn Ca. CAS NO 37625-56-2 is a specialized, low-molecular-weight tri-functional polyol derived from caprolactone monomers. This compound is valued for its excellent flexibility, hydrolytic stability, and compatibility with various polyurethane systems, making it a crucial building block for high-performance materials. It is primarily sought by formulators and manufacturers in the polyurethane elastomer, adhesive, sealant, and coating industries to enhance product durability and processing characteristics.

Application

• Polyurethane Elastomers: Used as a soft segment to impart flexibility, resilience, and low-temperature performance in cast, thermoplastic, and millable gums.
• Adhesives & Sealants: Serves as a key polyol component to improve adhesion, elongation, and moisture resistance in high-performance formulations.
• Coatings: Incorporated into polyurethane coatings for textiles, plastics, and metals to enhance flexibility, abrasion resistance, and weatherability.
• Biomedical Polymers: Utilized in the synthesis of biodegradable and biocompatible polymers for controlled drug delivery and tissue engineering scaffolds.
• Resin Modification: Acts as a reactive modifier for other polymer systems (e.g., epoxies, polyesters) to tailor toughness and impact resistance.
• 3D Printing Materials: Employed in the development of flexible and durable photopolymer resins for stereolithography (SLA) and digital light processing (DLP).

Quality Control

Our Polycaprolactone Triol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent hydroxyl value, acid value, viscosity, and water content meet precise specifications. Certificates of Analysis (COA) detailing these parameters are provided with every shipment to guarantee supply reliability and product performance for your critical applications.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential degradation.
