From modified methylaluminoxanes (MMAO's) to isobutylaluminoxanes (IBAO's), we supply the world's largest range of aluminoxanes for use in single-site catalyst technology.

Our MMAO's contain modifiers, which provide superior stability for long-term storage. Modifiers also often provide excellent solubility in aliphatic hydrocarbons.

Due to the difficulty in production and handling, aluminoxanes are only offered as a hydrocarbon solution. Concentrations depend on properties of the aluminoxane, but solutions typically contain 7 wt% on soluble aluminum basis, corresponding to an aluminoxane concentration of about 15-19%.
