Featured applications
Our metal alkyls and complex metalorganics serve critical roles across diverse polymer and fine chemical processes.
Polypropylene Production
TEAL and TIBAL serve as essential co-catalysts in Ziegler-Natta polypropylene polymerization, enabling precise control over stereoregularity and polymer properties.
Polyethylene & LDPE
Metal alkyls activate catalyst systems for high-pressure and gas-phase polyethylene processes, delivering consistent melt flow and molecular weight distribution.
Metallocene & Single-Site Catalysts
Modified methylaluminoxanes (MMAO) activate metallocene catalysts for precision polymer engineering — enabling POE, EPDM, and advanced elastomers.
Pharmaceuticals & Fine Chemicals
Metal alkyls facilitate asymmetric reduction, addition, alkylation, and deprotonation steps in pharmaceutical and fine chemical synthesis with high selectivity.
Product categories
Four major families of metalorganic products, covering aluminum, magnesium, zinc, and boron-based chemistry.
Aluminum Alkyls
Triethylaluminum (TEAL), triisobutylaluminum (TIBAL), diethylaluminum chloride (DEAC), and ethylaluminum sesquichloride (EASC). Essential co-catalysts for Ziegler-Natta polymerization.
Magnesium Alkyls
Butylethylmagnesium (BEM/MAGALA®) and other magnesium alkyl solutions. Used as magnesium sources in Ziegler-Natta catalyst preparation for PE and PP production.
Zinc Alkyls
Diethylzinc (DEZ) and other zinc alkyl compounds. Used as chain shuttling agents in block copolymer synthesis and as crosslinking facilitators.
Boron Compounds
Organo-boron reagents for specialty polymerization and fine chemical synthesis. Includes triethylborane (TEB) and borate esters for specific catalyst systems.
Modified Methylaluminoxanes
The world's broadest range of modified aluminoxanes for single-site catalyst activation. MMAO-3A, MMAO-7, and custom MMAO formulations for metallocene and post-metallocene systems.
Complex Metalorganic Catalysts
Custom-manufactured ligands, metallocenes, and single-site catalyst systems. Designed to customer specifications for advanced polyolefin and specialty polymer production.
