　hydroxyisopropyl benzene.

。Packaging and transport

　The standard packaging is a box for 25 kg peroxide formulation.

　Both packaging and transport meet the international regulations. For the availability of 

　other packed quantities consult your Lanzhou Auxiliary Agent Plant sales office.

　LQ-BPIB is exempted as Organic peroxide, Division 5.2.

Keep away from open fire, sparks and other sources of heat or ignition. Avoid contact with 

　reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, 

　driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information

　on the safe storage, use and handling of LQ-BPIB This information should be thoroughly 

　reviewed prior to acceptance of this product.

。Applications

Rubber compounds containing LQ-BPIB have excellent scorch safety, under certain conditions 

one step mixing is possible.
