Polycaprolactone CAS 24980-41-4 Overview
Polycaprolactone (PCL, CAS 24980-41-4) is a biodegradable aliphatic polyester supplied by Unilong as white round particles at 99% purity. It is used across polyurethane and TPU formulation, hot melt adhesives, biodegradable film and packaging, 3D printing filament production, and medical thermoplastic manufacturing.
Unilong supplies PCL for industrial trial quantities through to bulk commercial volumes, with full specification, COA/TDS/SDS, and quotation support for buyers evaluating or scaling production.

Order Options for Trial and Commercial Supply
Buyers can begin with an industrial trial quantity to confirm processing performance before committing to bulk purchasing.
Trial sample — 50–500 g for initial material or process evaluation
Trial quantity — for material evaluation, formulation trial, or process trial ahead of production
Pilot order — for pre-production qualification and line trials
Standard purchase — for confirmed formulations moving into regular production
Bulk supply — for ongoing manufacturing demand, with repeat-order support
Custom requirements — specification or packaging adjustments can be discussed for qualifying orders
This structure lets manufacturers, compounders, and formulators validate PCL in their own process before scaling purchase volume.
Industrial Applications of Polycaprolactone
PCL for Polyurethane and TPU Applications
PCL is used as a soft-segment raw material in selected polyurethane (PU) and thermoplastic polyurethane (TPU) systems, supporting formulations for footwear outsoles, automotive protective film, elastomers, synthetic leather, coatings, and adhesives, where its crystallinity and flexibility contribute to elastomer performance.
PCL for Hot Melt Adhesives
PCL’s low melting point and compatibility with other resins support hot melt adhesive formulation for footwear adhesives, wood edge-banding, and industrial hot melt applications requiring strong bond strength and workable open time.
PCL for Biodegradable Films and Packaging
PCL is used in biodegradable film and flexible packaging formulations, including agricultural film, where biodegradability is a formulation requirement. Buyers developing food-contact packaging should confirm regulatory requirements for their specific finished application (see Quality Control and Technical Documents).
PCL for 3D Printing Filament
PCL’s low processing temperature supports FDM filament manufacturing for prototyping and custom thermoplastic components, including industrial filament production runs requiring consistent melt behavior.
PCL for Medical Thermoplastic Products
PCL is used in the manufacture of medical thermoplastic products such as orthopedic splints and radiotherapy positioning materials, where its low melting point allows hand-moldable or low-temperature-formed thermoplastic parts.
PCL Price and Quotation
PCL pricing depends on several factors. To receive an accurate quotation, please provide:
Required specification or grade
Order quantity — trial or bulk
Packaging preference
Delivery destination
Required documentation — COA / TDS / SDS
Custom or application-specific requirements
