Initiators for PVC

We offer a wide range of organic peroxide initiators for the production of polyvinylchloride (PVC). Our organic peroxides are used as single initiator or in a combination of initiators in order to optimize polymerization rate.

The most important criteria for initiator selection are peroxide reactivity, initiator safety and physical form.

Peroxide reactivity

The first and maybe most important criterion for initiator selection is reactivity. The reactivity can be expressed by the initiator half life. The half-life is the time required to reduce the original initiator content at a given temperature by 50%.

Initiator safety

Organic peroxides are unstable chemical compounds, decomposing at relatively low temperatures. They can, however, be handled and stored safely if proper precautions are followed. Although a number of organic peroxides can be safely stored at ambient temperatures, most require some form of temperature control.

Physical form

Organic peroxides are available in different formulations. Water based peroxide suspensions and emulsions are much safer than the usual solid, liquid or solvent based peroxides. Peroxide suspensions and emulsions can be dosed automatically and can be applied in closed reactor technology. Additionally, water based peroxide formulations can be transported in bulk or intermediate bulk containers (IBC's).
