Description

Poly(Toluene 2,4-Diisocyanate-Polycaprolactonediol-Ethylenediamine) Copolymer is a high-performance, segmented polyurethane-urea copolymer synthesized from toluene diisocyanate (TDI), polycaprolactone diol (PCL), and ethylenediamine. This material matters for its exceptional combination of mechanical strength, elasticity, and biocompatibility, derived from its unique hard and soft segment morphology. It is primarily needed by manufacturers in the medical device, specialty adhesive, and advanced elastomer industries seeking durable and versatile polymeric materials.

Application

• Medical Device Coatings: Used as a biocompatible coating for catheters, guidewires, and implants to enhance lubricity and blood compatibility.
• High-Performance Adhesives & Sealants: Serves as a key component in flexible, moisture-curing adhesives for automotive, construction, and aerospace applications.
• Specialty Elastomers and Fibers: Employed in the production of spandex-like fibers, elastic films, and impact-resistant rubber parts.
• Drug Delivery Matrices: Utilized in controlled-release systems due to its biodegradable polycaprolactone segments and tunable degradation profile.
• Protective & Functional Coatings: Applied as a tough, flexible protective layer for textiles, industrial equipment, and electronic components.
• Tissue Engineering Scaffolds: Investigated for use as biodegradable scaffolds in regenerative medicine, supporting cell growth and tissue formation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent premature hydrolysis or property degradation. Keep away from strong acids, bases, and oxidizing agents.
