Description

2-Oxepanone, Polymer With 1,4-Cyclohexanedimethanol is a high-performance, aliphatic polyester copolymer derived from caprolactone and cyclohexanedimethanol. This material is engineered to offer an exceptional balance of flexibility, toughness, and hydrolytic stability, making it a critical component in advanced material formulations. It is primarily sought after by manufacturers in the medical device, specialty adhesive, and high-durability coating industries for its biocompatibility and superior mechanical properties.

Application

• Biomedical Implants & Devices: Used as a key polymer matrix for bioresorbable sutures, drug delivery scaffolds, and soft tissue engineering due to its biocompatibility and controlled degradation profile.
• High-Performance Adhesives & Sealants: Serves as a flexible, durable backbone in polyurethane-based adhesives for automotive, construction, and aerospace applications requiring strong bonding and environmental resistance.
• Specialty Coatings & Inks: Imparts flexibility, adhesion, and chemical resistance to protective coatings for wires, textiles, and industrial components.
• Thermoplastic Polyurethane (TPU) Elastomers: Acts as a soft segment to enhance the low-temperature flexibility, tear strength, and hydrolysis resistance of TPUs used in footwear, hoses, and gaskets.
• Polymer Modification & Blending: Employed as a compatibilizer or impact modifier to improve the toughness and processability of rigid engineering plastics like polycarbonate or nylon.

Quality Control

Our production of 2-Oxepanone, Polymer With 1,4-Cyclohexanedimethanol adheres to stringent quality management protocols. Each batch is characterized for critical parameters including molecular weight distribution (GPC), hydroxyl value, acid value, and thermal properties (DSC) to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant frameworks for industrial and biomedical 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 polymer is hygroscopic (moisture-sensitive); prolonged exposure to atmospheric humidity should be avoided to prevent property changes. Keep away from strong oxidizers and high heat sources.
