tert-amyl peroxypivalate

Tert-amyl peroxypivalate (CAS 29240-17-3), also known as tert-pentyl peroxypivalate, is an organic peroxide used as a free-radical initiator in polymer manufacturing.

Where is tert-amyl peroxypivalate used?

• Plastics and polymer production: initiates bulk, suspension, and solution polymerization of vinyl acetate, acrylates, and styrene
• Rubber compounding: cross-linking agent that cures elastomers
• Coatings: supports radical-cure systems
• Adhesives and sealants: peroxide-cured systems
• It decomposes at low temperatures to initiate polymerization with controlled radical generation.

Good to know: Thermally sensitive; distributed under temperature-controlled conditions and classified under regulated transport requirements for organic peroxides.

Commercial specifications

• Active oxygen concentrations suited for safe handling and transport
