Description

Dilapan CAS NO 123535-69-3 is a high-purity synthetic polymer, specifically a hydrogel, known for its unique swelling properties and biocompatibility. This material is critical for applications requiring precise, controlled expansion and moisture absorption. It is primarily utilized in the medical device and pharmaceutical industries, where reliable performance and material consistency are paramount for product safety and efficacy.

Application

• Medical Devices: A key component in cervical dilators and other gynecological medical devices due to its predictable, controlled swelling behavior.
• Pharmaceutical Formulations: Used as an excipient in controlled-release drug delivery systems and as a disintegrant in solid dosage forms.
• Wound Care: Employed in advanced hydrogel wound dressings for maintaining a moist healing environment and managing exudate.
• Laboratory Research: Serves as a model hydrogel in biomedical research for studying swelling kinetics, drug release profiles, and biomaterial interactions.
• Personal Care: Incorporated into cosmetic and personal care products for its moisture-retention and texture-modifying properties.

Quality Control

Our Dilapan is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability for critical medical applications. Quality control includes testing for key parameters such as swelling ratio, gel strength, residual monomers, and biocompatibility according to relevant pharmacopeial guidelines and ISO 10993 standards. A comprehensive Certificate of Analysis (COA) detailing purity, performance, and safety specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent premature moisture absorption which can alter its performance characteristics.
