Description

Poly(Hydroxyethylmethacrylate Bisglycolacrylate) is a high-performance, cross-linked polymer derived from functional methacrylate monomers. This material is engineered to provide exceptional biocompatibility, controlled hydrophilicity, and robust mechanical properties, making it a critical component in advanced material science. It is primarily sought by manufacturers in the medical device, pharmaceutical, and specialty coatings industries for applications requiring precise material performance.

Application

• Hydrogel Contact Lenses and Ophthalmic Devices: As a key matrix material for its high water content, oxygen permeability, and biocompatibility.
• Drug Delivery Systems: Used in controlled-release matrices and transdermal patches due to its tunable swelling and degradation properties.
• Medical Implants and Tissue Engineering Scaffolds: Provides a supportive, biocompatible structure for cell growth and integration.
• Wound Care Dressings: Utilized in hydrogel dressings for maintaining a moist wound environment and absorbing exudate.
• Dental Materials: Incorporated into restorative resins and cavity liners for improved adhesion and durability.
• Biomedical Sensor Coatings: Acts as a permeable, biocompatible layer for implantable or wearable sensors.
• Personal Care Products: Used in formulations for sustained fragrance release or as a thickening/gelling agent.
• Chromatography Media: Serves as a base material for hydrophilic interaction chromatography (HILIC) columns.

Quality Control

Our production of Poly(Hydroxyethylmethacrylate Bisglycolacrylate) adheres to stringent quality management systems, ensuring batch-to-batch consistency for critical applications. Each lot is characterized for key parameters including degree of cross-linking, swelling ratio, residual monomer content, and molecular weight distribution. Certificates of Analysis (COA) documenting purity, physicochemical properties, and biocompatibility test results (where applicable) are provided. We support compliance with relevant ISO 13485 (for medical devices) and cGMP guidelines for pharmaceutical applications.

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); keep the container tightly sealed to prevent absorption of atmospheric moisture, which can alter its properties. Keep away from strong oxidizing agents.
