Description

Hilafilcon B is a high-purity, hydrophilic contact lens material belonging to the class of silicone hydrogel polymers. This advanced material is engineered to provide exceptional oxygen permeability and moisture retention, which are critical for ocular health and comfort. It is primarily utilized by manufacturers in the medical device and ophthalmic industries for the production of next-generation soft contact lenses.

Application

• Primary material for the manufacture of silicone hydrogel soft contact lenses.
• Used in the development of extended-wear and daily disposable contact lenses.
• Key component in ophthalmic medical devices requiring high oxygen transmissibility (Dk/t).
• Employed in biomedical research for advanced polymer and hydrogel studies.
• Potential applications in other medical device coatings requiring biocompatibility and hydrophilicity.

Quality Control

Our Hilafilcon B is produced under strict quality management systems to ensure it meets the stringent requirements for medical device manufacturing. Each batch is tested against comprehensive specifications for purity, monomer content, and functional performance. Certificates of Analysis (COA) detailing results for identity, assay, and critical impurities are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
