Triethylaluminum (TEAI) co-catalyst

Triethylaluminum (TEAl) – High-Efficiency Co-Catalyst

Precision Performance for Olefin Polymerization

B.F.S offers high-purity Triethylaluminum (TEAl), a widely used co-catalyst essential for the activation of Ziegler-Natta and metallocene catalysts in the polymerization of olefins. As a powerful alkylating agent, TEAl enhances the efficiency, selectivity, and activity of catalyst systems in the production of polyethylene, polypropylene, and other specialty polyolefins.

⚙️ Key Applications

1. Ziegler-Natta Catalyst Systems

Acts as a co-catalyst by reducing titanium centers (e.g., TiCl₄) and generating active polymerization sites.
Controls molecular weight, stereoregularity, and polymer microstructure.

2. Metallocene Catalysis

Essential for activating Group IV metal-based catalysts (e.g., zirconium, hafnium) in single-site catalyst systems.
Allows for tunable polymer architecture, including block copolymers and narrow molecular weight distributions.

3. Alkylation Agent in Fine Chemistry

Used in alkylation and organometallic synthesis, particularly in the production of high-performance intermediates.
