Description

Octa(γ-Chloropropyl) Poss is a specialized polyhedral oligomeric silsesquioxane (POSS) derivative functionalized with eight chloropropyl groups. This compound serves as a high-performance, multifunctional building block for creating advanced hybrid organic-inorganic materials with enhanced thermal stability and mechanical properties. It is essential for R&D and production in industries such as specialty polymers, high-temperature resins, and advanced coatings, where precise molecular architecture is required to impart specific characteristics.

Application

• Advanced Polymer Modification: Acts as a reactive nanoscale filler or co-monomer to enhance the thermal stability, flame retardancy, and mechanical strength of engineering plastics, silicones, and epoxy resins.
• Hybrid Material Synthesis: Serves as a core scaffold for constructing precisely defined nanostructured materials, including porous frameworks, dendrimers, and star-shaped polymers.
• Surface Functionalization Agent: Used to modify surfaces (e.g., silica, metals, polymers) to introduce reactive chloropropyl groups for subsequent grafting or coupling reactions.
• Catalyst and Ligand Support: Provides a robust, inorganic-organic hybrid platform for immobilizing catalysts or creating novel ligand systems for catalytic applications.
• Specialty Additives: Incorporated into formulations for coatings, adhesives, and sealants to improve performance under extreme conditions.

Quality Control

Our Octa(γ-Chloropropyl) Poss is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR, FT-IR, and HPLC, to verify chemical structure and purity. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture.
