Description

Dimethylsilylbis(9-Fluorenyl)Zirconium Dichloride is a highly active, single-site metallocene catalyst precursor essential for advanced polyolefin synthesis. Its value lies in enabling precise control over polymer microstructure, including tacticity, molecular weight, and comonomer incorporation, which is critical for developing high-performance materials. This compound is primarily needed by R&D chemists and process engineers in the petrochemical and polymer industries focused on creating specialty plastics, elastomers, and other tailored polyolefins.

Application

• Catalyst Component for Polyolefin Production: Serves as a key precursor for homogeneous Ziegler-Natta catalysts used in the polymerization of ethylene and propylene.
• Synthesis of Specialty Polyethylenes: Enables the production of linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) with tailored properties.
• Development of Advanced Polypropylenes: Used in catalyst systems for synthesizing isotactic, syndiotactic, or atactic polypropylene with specific performance characteristics.
• Olefin Copolymerization: Facilitates the copolymerization of ethylene with higher α-olefins (e.g., 1-butene, 1-hexene) to create impact-resistant and flexible copolymers.
• Research & Development: A vital tool in academic and industrial R&D for exploring new catalytic processes and novel polymer architectures.
• Fine Chemical Synthesis: May be employed as an organometallic reagent in specialized organic transformations.

Quality Control

Our Dimethylsilylbis(9-Fluorenyl)Zirconium Dichloride is manufactured and handled under stringent quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot undergoes comprehensive analysis, including NMR spectroscopy and elemental analysis, to verify identity and purity. Certificates of Analysis (COA) detailing all relevant specifications are available upon request to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C (refrigerated) to maintain stability. Due to its moisture-sensitive and easily oxidized nature, the container should only be opened in a controlled, dry, and oxygen-free environment.
