Description

Peg Poss Cage Mixture CAS NO 1255649-48-9 is a specialized polyhedral oligomeric silsesquioxane (POSS) derivative functionalized with polyethylene glycol (PEG) chains. This advanced hybrid material is engineered to combine the robust, cage-like inorganic silica core of POSS with the solubility, biocompatibility, and tunable properties of organic PEG polymers. It is a critical component for researchers and formulators in advanced materials science seeking to enhance the performance and processability of polymers, coatings, and biomedical systems. Key industries that utilize this innovative mixture include high-performance composites, nanotechnology, drug delivery, and specialty coatings.

Application

• Polymer Nanocomposites: Acts as a nano-reinforcing agent and property modifier to improve thermal stability, mechanical strength, and reduce flammability in engineering plastics, epoxies, and elastomers.
• Biomedical & Drug Delivery: Serves as a functional platform for creating biocompatible carriers, hydrogels, and surface coatings for controlled drug release, diagnostics, and tissue engineering scaffolds.
• Specialty Coatings & Adhesives: Enhances surface properties, adhesion, scratch resistance, and provides low surface energy for release coatings and hydrophobic films.
• Advanced Material Additive: Used to tailor rheological properties, increase dispersion stability, and introduce inorganic character into organic matrices for hybrid materials.
• Personal Care & Cosmetics: Employed in formulations to improve film-forming properties, texture, and delivery of active ingredients in skincare products.
• Electronics & Optics: Utilized in the development of low-k dielectric materials, encapsulants, and optical films due to its tunable refractive index and thermal properties.

Quality Control

Our Peg Poss Cage Mixture is produced under a strict quality management system. Each batch undergoes comprehensive analytical characterization to ensure consistency and performance. Key parameters monitored include PEG functionalization degree, cage structure integrity, molecular weight distribution, and purity. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment to guarantee it meets your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent moisture uptake and potential degradation.
