XJ-LPO ,Dilauroyl peroxide , is an initiator for (co)polymerization of styrene, ethylene, vinyl chloride, vinylidene chloride and (meth)acrylates. It is also used as an initiator for curing acrylic solid surface at elevated temperatures.

Application 

● LPO is frequently used in polymerization processes, with a working temperature range between 60°C and 75°C. In many cases, it is combined with higher reactivity peroxides, such as Bis(4-tert-butylcyclohexyl) peroxydicarbonate or tert-butyl peroxyneodecanoate (1,1,3,3-tetramethylbutyl ester), to broaden its reactivity range and improve efficiency.

● Although LPO has lower solubility, which often leads to its substitution by peroxynonanoyl, its advantage lies in its ability to be stored at room temperature, making it a practical choice for certain high-pressure polyethylene applications.

● LPO is also a favored initiator for the polymerization of acrylates, with reaction temperatures ranging from 60°C to 90°C. It’s often used as a safer alternative to more toxic compounds, such as azo bisisobutyronitrile (AIBN).

● When used alongside compounds like 1,1-Di(tert-butylperoxy)-3,3,5-trimethylcyclohexane (XJ-TMCH), LPO significantly enhances initiation effects, making it ideal for various industrial polymerization processes.
