Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The relative density of Polymethylaluminoxane 13 wt % Al in toluene is determined at different temperatures. The results of the relative density at the different temperatures show a linear regression with the equation:

Relative density= -0.000815x+0.919413

Using this equation the relative density at the temperature of 20°C is calculated to be 0.903113.
Executive summary:

Using this equation the relative density at the temperature of 20°C is calculated to be 0.903113.

Description of key information

Using this equation the relative density at the temperature of 20°C is calculated to be 0.903113.

Key value for chemical safety assessment

Relative density at 20C:
0.903
