Storage Conditions for Organic Peroxides

Limiting the heat exposure of the product and preventing contamination can minimize the probability of a peroxide decomposition. Temperature control is the most critical control measure in preserving quality and preventing a runaway reaction.

We also have clear guidelines for design of storage buildings and fire fighting, and do's and don'ts for storage of organic peroxides.

Safety temperatures

Although a number of organic peroxides can safely be stored at room temperature, most require some form of temperature control. The maximum temperature allowed by the regulatory agencies is the control temperature (Tc). The emergency temperature (Tem) is the temperature at which emergency procedures must be implemented.

Both the control and emergency temperature are derived from the SADT:

Quality temperatures

For a longer shelf life, we recommend you to store our products at lower temperatures than the control temperatures. This recommended maximum storage temperature (Ts max.) is printed on the product label as well as on specific Product Data Sheets (PDS) and Material Safety Data Sheets (MSDS).

A minimum storage temperature (Ts min.) is given if phase separation, crystallization or solidification of the products is known to occur below a specific temperature. Also for safety reasons we recommend you to store the product above the Ts min. indicated.
