Almost all the decomposition of azo initiators is a first-order reaction, only one kind of free radical is formed, and there is no side reaction, so it is widely used in industrial production and scientific research. The azo initiator has stable properties and is convenient for storage and transportation. However, it needs to be refrigerated during transportation, and to prevent violent friction, collision, and explosion. This product is mainly used for bulk polymerization, suspension polymerization and solution polymerization.


It can be used as an initiator for the polymerization of ethylenic monomers such as methyl methacrylate, and can also be used as a foaming agent.

Storage conditions/storage methods

This product is sealed and stored at 2-6°C to prevent impact and friction.

Product packaging

1kg packed in aluminum foil bag, 50kgs per cardboard drum, for details please confirem with sales.

Notes on transportation and storage

For transportation in ice packs, it is required to be sealed and stored at a low temperature below 2-6 °C.
