Dicumyl peroxide is an organic compound with the formula (C6H5CMe2O)2 (Me = CH 3 ). Classified as a dialky peroxide, it is produced on a large scale industrially for use in polymer chemistry. It serves as an initiator and crosslinking agent in the production of low density polyethylene. [2]
In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group ( R−O−O−R′ ). If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article. The O−O bond of peroxides easily breaks, producing free radicals of the form RO• (the dot represents an unpaired ...

Cumene hydroperoxide is an intermediate in the cumene process for producing phenol and acetone from benzene and propene . Cumene hydroperoxide is a free radical initiator for production of acrylates. [5] Cumene hydroperoxide is involved as an organic peroxide in the manufacturing of propylene oxide by the oxidation of propylene.
Peroxide crosslinking (PE-Xa): The crosslinking of polyethylene using peroxides (e.g. dicumyl peroxide or di-tert-butyl peroxide) is still of major importance. In the so-called Engel process , a mixture of HDPE and 2% [ 11 ] peroxide is at first mixed at low temperatures in an extruder and then crosslinked at high temperatures (between 200 °C ...

An uncured piece of liquid silicone rubber. Silicone rubber is an elastomer (rubber-like material) composed of silicone —itself a polymer —containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers, and ...
