CHP

CHP may be used for various polymerization reactions. It can be used in emulsion,solution and bulk polymerizations.In emulsion processes,it may be activated by organic-soluble or water-soluble reducing agents, or by metal compounds to achieve polymerization at room temperature or lower.

FAQ

What is organic peroxide?

Organic peroxide is a compound containing a peroxide functional group (-O-O-) attached to an organic molecule (containing carbon). These compounds are highly reactive due to the weak O-O bond, which easily breaks, releasing free radicals. They are often used as initiators in polymerization processes and in various industrial applications.

What are organic peroxides used for?

Organic peroxides are widely used as polymerization initiators, curing agents for resins, and crosslinking agents for elastomers and thermoplastics.

What should be noted when storing organic peroxides?

Organic peroxides are oxidizing and flammable substances and must be handled with caution. They should be stored in a cool, well-ventilated area with containers kept tightly closed, away from heat sources and open flames, and should not come into contact with rust. Keep them away from reducing agents, heavy metals, alkali metals, desiccants, accelerators, and other flammable chemicals. Product weighing should not be carried out inside the storage area. Always follow the storage temperature indicated on the product label.
