Bulk density, 20℃ : 400 kg/m³

。Half life data

　The most important characteristic of a crosslinking peroxide is its decomposition rate

　expressed by its half life (t) at various temperatures.

　For LQ-BPIB in a EPDM compound:

　t 0.1 hr 1 hr 10 hr

　at 169℃ 146℃ 117℃

　For LQ-BPIB Ts max. = 30℃

。Major decomposition products

　Methane, Acetone, tert-Butanol, Di(2-hydroxyisopropyl)benzene, Diacetylbenzene, Acetyl 2-

　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.

Typical Properties

This product can be used as crosslinking agent for chlorinated polyethylene, ethylene propylene diene monomer, ethylene vinyl acetate copolymer, silicone rubber, nitrile rubber, fluororubber and other plastics and rubber. 1. It is an excellent degradation agent for Polypropylene Degradation: it can be made into rheological polypropylene with low molecular weight and narrow molecular weight distribution and high melt index. It is a very important initiator for controllable rheological polypropylene. 2. It is the initiator of styrene polymerization. This product is an initiator for bulk polymerization of styrene, which is characterized by larger molecular weight of PS and high polymerization conversion. 3. It is the most common rubber vulcanizing agent: This product has excellent scorch safety. It is usually diluted with silicone oil or other neutral solvents or neutral fillers.
