tert-butyl peroxyacetate

Tert-butyl peroxyacetate (CAS 107-71-1), also known as tert-butyl peracetate and sold under the trade name Lupersol 70, is an organic peroxide used as a free-radical source in polymer manufacturing.

Where is tert-butyl peroxyacetate used?

• Plastics and polymer production: initiates free-radical polymerization of vinyl monomers including styrene, acrylates, and vinyl acetate, enabling molecular weight control
• Rubber and tire manufacturing: cross-linking agent to cure elastomers, improving mechanical strength and heat resistance
• Co-initiator in high-temperature polymerization systems where precise radical flux is required
• Formulators working with polyethylene and specialty resins select it for grafting reactions where other peroxides would decompose too rapidly.

Commercial specifications

• Liquid solution, typically 75% active concentration in a diluent to reduce handling hazards
• Supply governed by peroxide-specific transport and storage regulations
• Packaging ranges from small drums to IBC containers
