Triisobutylaluminum (TIBA)

Triisobutylaluminum (TIBA) is a pyrophoric liquid supplied undiluted or as a solution in a compatible hydrocarbon solvent.


Triisobutylaluminum (TIBA) is primarily used as a cocatalyst in the Ziegler-Natta polymerization of olefins, as a reducing agent in certain organic reduction reactions and as a chemical intermediate.


Triisobutylaluminum (TIBA) is a Ziegler-Natta catalyst used for the manufacture of high density and linear low density polyethylene, polypropylene, and in the manufacture of synthetic elastomers.


As a global supplier of aluminum alkyls, we have an intense focus on safety and an active product stewardship program involving our customers. Utilizing our in-depth working experience and manufacturing knowledge of organometallics, our Alkyls Technical Service (ATS) teams based in both the USA and India are available to provide technical assistance, emergency response, on-site safety audits and training to ensure the safe handling and use of metal alkyls.

Gulbrandsen can provide not only neat aluminum alkyls but can utilize its cost effective manufacturing facilities to provide metal alkyl solutions in various hydrocarbon solvents in any concentration required. We can also manufacture custom alkyl mixtures to match your particular requirements.
