Dilauroyl Peroxide - Cas No: 105-74-8, Density: 1.02 G/cmâ³, Solid Form, White Crystalline, Usage In Polymer Production, Thermally Unstable Oxidizer

Dilauroyl peroxide or LPO is commonly used as a polymerization initiator for various compounds, including ethylene, styrene, vinyl chloride, vinylidene chloride, acrylates, and methacrylates. Its versatility makes it an important component in initiating polymer reactions, especially in the production of plastics and resins.

• LPO is frequently used in polymerization processes, with a working temperature range between 60C and 75C. 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 60C to 90C. Its often used as a safer alternative to more toxic compounds, such as azobisisobutyronitrile (AIBN).
• When used alongside compounds like 1,1-Di(tert-butylperoxy)-3,3,5-trimethylcyclohexane (LQ-CH335), LPO significantly enhances initiation effects, making it ideal for various industrial polymerization processes.
