Description

Methyloleateperoxide CAS NO 26567-90-8 is a specialized organic peroxide primarily used as a polymerization initiator and cross-linking agent. Its controlled reactivity makes it a critical component for initiating free-radical reactions in polymer synthesis and resin curing processes. This product is essential for manufacturers in the polymer, coatings, and composite materials industries seeking efficient and reliable initiators for their production systems.

Application

• Primary initiator for the polymerization of vinyl monomers such as styrene, methyl methacrylate, and vinyl acetate.
• Cross-linking agent for unsaturated polyester resins (UPR) in the production of fiberglass reinforced plastics (FRP) and sheet molding compounds (SMC).
• Curing agent for acrylic and other thermoset resins used in coatings, adhesives, and gel coats.
• Used in the synthesis of specialty polymers where controlled decomposition temperature and radical generation are required.
• Employed in the modification of polymers to achieve specific mechanical or thermal properties.
